+ * Please refer to file 'xil_errata.h' for errata
+ * description.
+ * 3.10a asa 05/04/13 Added support for L2 cache in MicroBlaze BSP. The older
+ * cache APIs were corresponding to only Layer 1 cache
+ * memories. New APIs were now added and the existing cache
+ * related APIs were changed to provide a uniform interface
+ * to flush/invalidate/enable/disable the complete cache
+ * system which includes both L1 and L2 caches. The changes
+ * for these were done in:
+ * src/microblaze/xil_cache.c and src/microblaze/xil_cache.h
+ * files.
+ * Four new files were added for supporting L2 cache. They are:
+ * microblaze_flush_cache_ext.S-> Flushes L2 cache
+ * microblaze_flush_cache_ext_range.S -> Flushes a range of
+ * memory in L2 cache.
+ * microblaze_invalidate_cache_ext.S-> Invalidates L2 cache
+ * microblaze_invalidate_cache_ext_range -> Invalidates a
+ * range of memory in L2 cache.
+ * These changes are done to implement PR #697214.
+ * 3.10a asa 05/13/13 Modified cache disable APIs at src/cortexa9/xil_cache.c to
+ * fix the CR #706464. L2 cache disabling happens independent
+ * of L1 data cache disable operation. Changes are done in the
+ * same file in cache handling APIs to do a L2 cache sync
+ * (poll reg7_?cache_?sync). This fixes CR #700542.
+ * 3.10a asa 05/20/13 Added API/Macros for enabling and disabling nested
+ * interrupts for ARM. These are done to fix the CR#699680.
+ * 3.10a srt 05/20/13 Made changes in cache maintenance APIs to do a proper cach
+ * sync operation. This fixes the CR# 716781.

+ * for armcc toolchain.
+ * Modified asm_vectors.S (gcc) and asm_vectors.s (armcc) to
+ * fix issues related to NEON context saving. The assembly
+ * routines for IRQ and FIQ handling are modified.
+ * Deprecated the older BSP (3.10a).
+ * 3.11a asa 09/22/13 Fix for CR#732704. Cache APIs are modified to avoid
+ * various potential issues. Made changes in the function
+ * Xil_SetAttributes in file xil_mmu.c.
+ * 3.11a asa 09/23/13 Added files xil_misc_psreset_api.c and xil_misc_psreset_api.h
+ * in src\cortexa9 and src\microblaze folders.
+ * 3.11a asa 09/28/13 Modified the cache APIs (src\cortexa9) to fix handling of
+ * L2 cache sync operation and to fix issues around complete
+ * L2 cache flush/invalidation by ways.
+ * 3.12a asa 10/22/13 Modified the files xpseudo_asm_rvct.c and xpseudo_asm_rvct.h
+ * to fix linking issues with armcc/DS-5. Modified the armcc
+ * makefile to fix issues.
+ * 3.12a asa 11/15/13 Fix for CR#754800. It fixes issues around profiling for MB.
+ * 4.0 hk 12/13/13 Added check for STDOUT_BASEADDRESS where outbyte is used.
+ * 4.0 pkp 22/01/14 Modified return addresses for interrupt handlers (DataAbortHandler
+ * and SWIHandler) in asm_vector.S (src\cortexa9\gcc\ and
+ * src\cortexa9\armcc\) to fix CR#767251
+ * 4.0 pkp 24/01/14 Modified cache APIs (Xil_DCacheInvalidateRange and
+ * Xil_L1DCacheInvalidate) in xil_cache.c (src\cortexa9) to fix the bugs.
+ * Few cache lines were missed to invalidate when unaligned address
+ * invalidation was accommodated in Xil_DCacheInvalidateRange.
+ * In Xil_L1DCacheInvalidate, while invalidating all L1D cache
+ * stack memory (which contains return address) was invalidated. So
+ * stack memory is flushed first and then L1D cache is invalidated.
+ * This is done to fix CR #763829
+ * 4.0 adk 22/02/2014 Fixed the CR:775379 removed unnecessay _t(unit32_t etc) from
+ * mblaze_nt_types.h file and replace uint32_t with u32 in the
+ * profile_hist.c to fix the above CR.
+ * 4.1 bss 04/14/14 Updated driver tcl to remove _interrupt_handler.o from libgloss.a
+ * instead of libxil.a and added prototypes for

+ * 5.3 pkp 10/07/15 Modified cortexa9/xil_cache.c file to change cache API so that L2 Cache
+ * functionalities are avoided for the OpenAMP slave application(when
+ * USE_AMP flag is defined for BSP) as master CPU would be utilizing L2
+ * cache for its operation. Also file operations such as read, write,
+ * close, open are also avoided for OpenAMP support(when USE_AMP flag is
+ * defined for BSP) because XilOpenAMP library contains own file operation.
+ * The xil-crt0.S file is modified for not initializing global timer for
+ * OpenAMP application as it might be already in use by master CPU

+ * as per the toolchain update
+ * 5.4 pkp 12/01/16 Changed common/xplatform_info.* to add platform information support
+ * for Cortex-A53 32bit mode
+ * 5.4 pkp 28/01/16 Modified cortexa53/32bit/sleep.c and usleep.c & cortexa53/64bit/sleep.c
+ * and usleep.c to correct routines to avoid hardcoding the timer frequency,
+ * instead take it from xparameters.h to properly configure the timestamp
+ * clock frequency
+ * 5.4 asa 29/01/16 Modified microblaze/mb_interface.h to add macros that support the

+ * 5.4 asa 25/02/16 Made changes in xil-crt0.S for R5, A53 64 and 32 bit BSPs, to replace
+ * _exit with exit. We should not be directly calling _exit and should
+ * always use the library exit. This fixes the CR#937036.
+ * 5.4 pkp 25/02/16 Made change to cortexr5/gcc/boot.S to initialize the floating point
+ * registers, banked registers for various modes and enabled
+ * the cache ECC check before enabling the fault log for lock step mode

+ * registers initialization in boot code.
+ * 5.4 pkp 03/01/16 Updated the exit function in cortexr5/gcc/_exit.c to enable the debug

+ * 6.0 mus 08/03/16 Restructured the BSP to avoid code duplication across all BSPs.
+ * Source code directories specific to ARM processor's are moved to src/arm
+ * directory(i.e. src/cortexa53,src/cortexa9 and src/cortexr5 moved to src/arm/cortexa53,
+ * src/arm/cortexa9 and src/arm/cortexr5 respectively).Files xil_printf.c,xil_printf.h,
+ * print.c,xil_io.c and xil_io.h are consolidated across all BSPs into common file each and
+ * consolidated files are kept at src/common directory.Files putnum.c,vectors.c,vectors.h,
+ * xil_exception.c and xil_exception.h are consolidated across all ARM BSPs
+ * into common file each and consolidated files are kept at src/arm/common directory.
+ * GCC source files related to file operations are consolidated and kept
+ * at src/arm/common/gcc directory.
+ * All io interfacing functions (i.e. All variants of xil_out, xil_in )
+ * are made as static inline and implementation is kept in consolidated common/xil_io.h,
+ * xil_io.h must be included as a header file to access io interfacing functions.
+ * Added undefined exception handler for A53 32 bit and R5 processor
+ * 6.0 mus 08/11/16 Updated xtime_l.c in R5 BSP to remove implementation of XTime_SetTime API, since
+ * TTC counter value register is read only.
+ * 6.0 asa 08/15/16 Modified the signatures for functions sleep and usleep. This fixes
+ * the CR#956899.
+ * 6.0 mus 08/18/16 Defined ARMA53_32 flag in cortexa53/32bit/xparameters_ps.h and ARMR5 flag
+ * in cortexr5/xparameters_ps.h

+ * 6.0 mus 08/18/16 Removed unused variables from xil_printf.c and xplatform_info.c
+ * 6.0 mus 08/19/16 Modified xil_io.h to remove __LITTLE_ENDIAN__ flag check for all ARM processors
+ * 6.1 mus 11/03/16 Added APIs handle_stdin_parameter and handle_stdout_parameter in standalone tcl.
+ * ::hsi::utils::handle_stdin and ::hsi::utils::handle_stdout are taken as a base for
+ * these APIs and modifications are done on top of it to handle stdout/stdin
+ * parameters for design which doesnt have UART.It fixes CR#953681
+ * 6.1 nsk 11/07/16 Added two new files xil_mem.c and xil_mem.h for xil_memcpy
+ * 6.2 pkp 12/14/16 Updated cortexa53/64bit/translation_table.S for upper ps DDR. The 0x800000000 -
+ * 0xFFFFFFFFF range is marked normal memory for the DDR size defined in hdf
+ * and rest of the memory in that 32GB region is marked as reserved to avoid
+ * any speculative access
+ * 6.2 pkp 12/23/16 Added support for floating point operation to Cortex-A53 64bit mode. It modified
+ * asm_vectors.S to implement lazy floating point context saving i.e. floating point
+ * access is enabled if there is any floating point operation, it is disabled by
+ * default. Also FPU is initally disabled for IRQ and none of the floating point
+ * registers are saved during normal context saving. If IRQ handler does not require
+ * floating point operation, the floating point registers are untouched and no need
+ * for saving/restoring. If IRQ handler uses any floating point operation, then floating
+ * point registers are saved and FPU is enabled for IRQ handler. Then floating point
+ * registers are restored back after servicing IRQ during normal context restoring.
+ * 6.2 mus 01/01/17 Updated makefiles of R5 and a53 64 bit/32 bit processors to fix error in clean
+ * target.It fixes the CR#966900
+ * 6.2 pkp 01/22/17 Added support for EL1 non-secure execution and Hypervisor Baremetal for Cortex-A53
+ * 64bit Mode. If Hypervisor_guest is selected as true in BSP settings, BSP will be built
+ * for EL1 Non-secure, else BSP will be built for EL3. By default hypervisor_guest is
+ * as false i.e. default bsp is EL3.
+ * 6.2 pkp 01/24/17 Updated cortexa53/64bit/boot.S to clear FPUStatus variable to make sure that it
+ * contains initial status of FPU i.e. disabled. In case of a warm restart execution
+ * when bss sections are not cleared, it may contain previously updated value which
+ * does not hold true once processor resumes. This fixes CR#966826.
+ * 6.2 asa 01/31/17 The existing Xil_DCacheDisable API first flushes the
+ * D caches and then disables it. The problem with that is,
+ * potentially there will be a small window after the cache
+ * flush operation and before the we disable D caches where
+ * we might have valid data in cache lines. In such a
+ * scenario disabling the D cache can lead to unknown behavior.
+ * The ideal solution to this is to use assembly code for
+ * the complete API and avoid any memory accesses. But with
+ * that we will end up having a huge amount on assembly code
+ * which is not maintainable. Changes are done to use a mix
+ * of assembly and C code. All local variables are put in
+ * registers. Also function calls are avoided in the API to
+ * avoid using stack memory.
+ * 6.2 mus 02/13/17 A53 CPU cache system can pre-fetch catch lines.So there are
+ * scenarios when an invalidated cache line can get pre fetched to cache.
+ * If that happens, the coherency between cache and memory is lost
+ * resulting in lost data. To avoid this kind of issue either
+ * user has to use dsb() or disable pre-fetching for L1 cache
+ * or else reduce maximum number of outstanding data prefetches allowed.
+ * Using dsb() while comparing data costing more performance compared to
+ * disabling pre-fetching/reducing maximum number of outstanding data
+ * prefetches for L1 Cache.The new api Xil_ConfigureL1Prefetch is added
+ * to disable pre-fetching/configure maximum number of outstanding data
+ * prefetches allowed in L1 cache system.This fixes CR#967864.
+ * 6.2 pkp 02/16/17 Added xil_smc.c file to provide a C wrapper for smc calling which can be
+ * used by cortex-A53 64bit EL1 Non-secure application.
+ * 6.2 kvn 03/03/17 Added support thumb mode
+ * 6.2 mus 03/13/17 Fixed MISRA C mandatory standard violations in ARM cortexr5 and cortexa53 BSP.
+ * It fixes CR#970543
+ * 6.2 asa 03/16/17 Fix for CR#970859. For Mcroblaze BSP, when we enable intrusive
+ * profiling we see a crash. That is because the the tcl uses invalid
+ * HSI command. This change fixes it.
+ * 6.2 mus 03/22/17 Updated standalone tcl to generate xparameter XPAR_FPD_IS_CACHE_COHERENT, if
+ * any FPD peripheral is configured to use CCI.It fixes CR#972638
+ * 6.3 mus 03/20/17 Updated cortex-r5 BSP, to add hard floating point support.
+ * 6.3 mus 04/17/17 Updated Cortex-a53 32 bit BSP boot code to fix bug in
+ * the HW coherency enablement. It fixes the CR#973287
+ * 6.3 mus 04/20/17 Updated Cortex-A53 64 bit BSP boot code, to remove redundant write to the
+ * L2CTLR_EL1 register. It fixes the CR#974698
+ * 6.4 mus 06/08/17 Updated arm/common/xil_exception.c to fix warnings in C level exception handlers
+ * of ARM 32 bit processor's.
+ * 6.4 mus 06/14/17 Updated cortexa53/64bit/gcc/asm_vectors.S to fix bug in IRQInterruptHandler code
+ * snippet, which checks for the FPEN bit of CPACR_EL1 register.
+ * 6.4 ms 05/23/17 Added PSU_PMU macro in xplatform_info.c, xparameters.h to support
+ * XGetPSVersion_Info function for PMUFW.
+ * ms 06/13/17 Added PSU_PMU macro in xplatform_info.c to support XGetPlatform_Info
+ * function for PMUFW.
+ * 6.4 mus 07/05/17 Updated Xil_In32BE function in xil_io.h to fix bug.It fixes CR#979740.
+ * 6.4 mus 07/25/17 Updated a53 32 bit boot code and vectors to support hard floating point
+ * operations.Now,VFP is being enabled in FPEXC register, through boot code
+ * and FPU registers are being saved/restored when irq/fiq vector is invoked.
+ * 6.4 adk 08/01/17 Updated standalone tcl to generate xparameter XPAR_PL_IS_CACHE_COHERENT,
+ * if h/w design configured with HPC port.
+ * 6.4 mus 08/10/17 Updated a53 64 bit translation table to mark memory as a outer shareable for
+ * EL1 NS execution. This change has been done to support CCI enabled IP's.
+ * 6.4 mus 08/11/17 Updated a53 64 bit boot code to implement ARM erratum 855873.This fixes
+ * CR#982209.
+ * 6.4 asa 08/16/17 Made several changes in the R5 MPU handling logic. Added new APIs to
+ * make RPU MPU handling user-friendly. This also fixes the CR-981028.
+ * 6.4 mus 08/17/17 Updated XGet_Zynq_UltraMp_Platform_info and XGetPSVersion_Info APIs to read
+ * version register through SMC call, over EL1 NS mode. This change has been done to
+ * support these APIs over EL1 NS mode.
+ * 6.5 mus 10/20/17 Updated standalone.tcl to fix bug in mb_can_handle_exceptions_in_delay_slots proc,
+ * it fixes CR#987464.
+ * 6.6 mus 12/07/17 Updated cortexa9/xil_errata.h and cortexa9/xil_cache.c to remove Errata 753970.
+ * It fixes CR#989132.
+ * srm 10/18/17 Updated all the sleep routines in a9,a53,R5,microblaze. Now the sleep routines
+ * will use the timer specified by the user to provide delay. A9 and A53 can use
+ * Global timer or TTC. R5 can use TTC or the machine cycles. Microblaze can use
+ * machine cycles or Axi timer. Updated standalone.tcl and standalone.mld files
+ * to support the sleep configuration Added new API's for the Axi timer in
+ * microblaze and TTC in ARM. Added two new files, xil_sleeptimer.c and
+ * xil_sleeptimer.h in ARM for the common sleep routines and 1 new file,
+ * xil_sleepcommon.c in Standalone-common for sleep/usleep API's.
+ * 6.6 hk 12/15/17 Export platform macros to bspconfig.h based on the processor.
+ * 6.6 asa 1/16/18 Ensure C stack information for A9 are flushed out from L1 D cache
+ * or L2 cache only when the respective caches are enabled. This fixes CR-922023.
+ * 6.6 mus 01/19/18 Updated asm_vectors.S and boot.S in Cortexa53 64 bit BSP, to add isb
+ * after writing to cpacr_el1/cptr_el3 registers. It would ensure
+ * disabling/enabling of floating-point unit, before any subsequent
+ * instruction.
+ * 6.6 mus 01/30/18 Updated hypervisor enabled Cortexa53 64 bit BSP, to add xen PV console
+ * support. Now, xil_printf would use PV console instead of UART in case of
+ * hypervisor enabled BSP.
+ * 6.6 mus 02/02/18 Updated get_connected_if proc in standalone tcl to detect the HPC port
+ * configured with smart interconnect.It fixes CR#990318.
+ * 6.6 srm 02/10/18 Updated csu_wdt interrupt to the correct value. Fixes CR#992229
+ * 6.6 asa 02/12/18 Fix for heap handling for ARM platforms. CR#993932.
+ * 6.6 mus 02/19/18 Updated standalone.tcl to fix bug in handle_profile_opbtimer proc,
+ * CR#995014.
+ * 6.6 mus 02/23/18 Presently Cortex R5 BSP boot code is disabling the debug logic in
+* non-JTAG boot mode, when processor is in lockstep configuration.
+* This behavior is restricting application debugging in non-JTAG boot
+* mode. To get rid of this restriction, added new mld parameter
+* "lockstep_mode_debug", to enable/disable debug logic from BSP
+* settings. Now, debug logic can be enabled through BSP settings,
+* by modifying value of parameter "lockstep_mode_debug" as "true".
+* It fixes CR#993896.
+ * 6.6.mus 02/27/18 Updated Xil_DCacheInvalidateRange and
+* Xil_ICacheInvalidateRange APIs in Cortexa53 64 bit BSP, to fix bug
+* in handling upper DDR addresses.It fixes CR#995581.
+* 6.6 mus 03/12/18 Updated makefile of Cortexa53 32bit BSP to add includes_ps directory
+* in the list of include paths. This change allows applications/BSP
+* files to include .h files in include_ps directory.
+* 6.6 mus 03/16/18 By default CPUACTLR_EL1 is accessible only from EL3, it
+* results into abort if accessed from EL1 non secure privilege
+* level. Updated Xil_ConfigureL1Prefetch function in Cortexa53 64 bit BSP
+* to avoid CPUACTLR_EL1 access from privile levels other than EL3.
+* 6.6 mus 03/16/18 Updated hypervisor enabled BSP to use PV console, based on the
+* XEN_USE_PV_CONSOLE flag. By deafault hypervisor enabled BSP would
+* use UART console, PV console can be enabled by appending
+ "-DXEN_USE_PV_CONSOLE" to the BSP extra compiler flags.
