100 * Please refer to file 'xil_errata.h' for errata
102 * 3.10a asa 05/04/13 Added support for L2 cache in MicroBlaze BSP. The older
103 * cache APIs were corresponding to only Layer 1 cache
104 * memories. New APIs were now added and the existing cache
105 * related APIs were changed to provide a uniform interface
106 * to flush/invalidate/enable/disable the complete cache
107 * system which includes both L1 and L2 caches. The changes
108 * for these were done in:
109 * src/microblaze/xil_cache.c and src/microblaze/xil_cache.h
111 * Four new files were added for supporting L2 cache. They are:
112 * microblaze_flush_cache_ext.S-> Flushes L2 cache
113 * microblaze_flush_cache_ext_range.S -> Flushes a range of
114 * memory in L2 cache.
115 * microblaze_invalidate_cache_ext.S-> Invalidates L2 cache
116 * microblaze_invalidate_cache_ext_range -> Invalidates a
117 * range of memory in L2 cache.

120 * fix the CR #706464. L2 cache disabling happens independent
121 * of L1 data cache disable operation. Changes are done in the
122 * same file in cache handling APIs to do a L2 cache sync
123 * (poll reg7_?cache_?sync). This fixes CR #700542.
124 * 3.10a asa 05/20/13 Added API/Macros for enabling and disabling nested
125 * interrupts for ARM. These are done to fix the CR#699680.
126 * 3.10a srt 05/20/13 Made changes in cache maintenance APIs to do a proper cach
127 * sync operation. This fixes the CR# 716781.
128 * 3.11a asa 09/07/13 Updated armcc specific BSP files to have proper support
129 * for armcc toolchain.
130 * Modified asm_vectors.S (gcc) and asm_vectors.s (armcc) to
131 * fix issues related to NEON context saving. The assembly
132 * routines for IRQ and FIQ handling are modified.
133 * Deprecated the older BSP (3.10a).
134 * 3.11a asa 09/22/13 Fix for CR#732704. Cache APIs are modified to avoid
135 * various potential issues. Made changes in the function
136 * Xil_SetAttributes in file xil_mmu.c.
137 * 3.11a asa 09/23/13 Added files xil_misc_psreset_api.c and xil_misc_psreset_api.h
138 * in src\cortexa9 and src\microblaze folders.
139 * 3.11a asa 09/28/13 Modified the cache APIs (src\cortexa9) to fix handling of
140 * L2 cache sync operation and to fix issues around complete
141 * L2 cache flush/invalidation by ways.
142 * 3.12a asa 10/22/13 Modified the files xpseudo_asm_rvct.c and xpseudo_asm_rvct.h
143 * to fix linking issues with armcc/DS-5. Modified the armcc
144 * makefile to fix issues.
145 * 3.12a asa 11/15/13 Fix for CR#754800. It fixes issues around profiling for MB.
146 * 4.0 hk 12/13/13 Added check for STDOUT_BASEADDRESS where outbyte is used.
147 * 4.0 pkp 22/01/14 Modified return addresses for interrupt handlers (DataAbortHandler
148 * and SWIHandler) in asm_vector.S (src\cortexa9\gcc\ and
149 * src\cortexa9\armcc\) to fix CR#767251
150 * 4.0 pkp 24/01/14 Modified cache APIs (Xil_DCacheInvalidateRange and
151 * Xil_L1DCacheInvalidate) in xil_cache.c (src\cortexa9) to fix the bugs.
152 * Few cache lines were missed to invalidate when unaligned address
153 * invalidation was accommodated in Xil_DCacheInvalidateRange.
154 * In Xil_L1DCacheInvalidate, while invalidating all L1D cache
155 * stack memory (which contains return address) was invalidated. So
156 * stack memory is flushed first and then L1D cache is invalidated.
157 * This is done to fix CR #763829
158 * 4.0 adk 22/02/2014 Fixed the CR:775379 removed unnecessay _t(unit32_t etc) from
159 * mblaze_nt_types.h file and replace uint32_t with u32 in the
160 * profile_hist.c to fix the above CR.
161 * 4.1 bss 04/14/14 Updated driver tcl to remove _interrupt_handler.o from libgloss.a
162 * instead of libxil.a and added prototypes for
163 * microblaze_invalidate_cache_ext and microblaze_flush_cache_ext in
165 * 4.1 hk 04/18/14 Add sleep function.
166 * 4.1 asa 04/21/14 Fix for CR#764881. Added support for msrset and msrclr. Renamed

172 * common/xil_testcache.c
174 * 4.1 srt 06/27/14 Remove '#undef DEBUG' from src/common/xdebug.h, which allows to
175 * output the DEBUG logs when -DDEBUG flag is enabled in BSP.
176 * 4.2 pkp 06/27/14 Added support for IAR compiler in src/cortexa9/iccarm.
177 * Also added explanatory notes in cortexa9/xil_cache.c for CR#785243.
178 * 4.2 pkp 06/19/14 Asynchronous abort has been enabled into cortexa9/gcc/boot.s and
179 * cortexa9/armcc/boot.s. Added default exception handlers for data
180 * abort and prefetch abort using handlers called

229 * Xil_L2CacheInvalidateRange API. Xil_L1DCacheInvalidate and
230 * Xil_L2CacheInvalidate APIs are modified to flush the complete stack
231 * instead of just System Stack
232 * 5.1 pkp 14/05/15 Modified cortexa9/gcc/Makefile to keep a correct check of a compiler
233 * to update ECC_FLAGS and also take the compiler and archiver as specified

239 * to update ECC_FLAGS to fix a bug introduced during new version creation
241 * 5.3 pkp 10/07/15 Modified cortexa9/xil_cache.c file to change cache API so that L2 Cache
242 * functionalities are avoided for the OpenAMP slave application(when
243 * USE_AMP flag is defined for BSP) as master CPU would be utilizing L2
244 * cache for its operation. Also file operations such as read, write,
245 * close, open are also avoided for OpenAMP support(when USE_AMP flag is
246 * defined for BSP) because XilOpenAMP library contains own file operation.
247 * The xil-crt0.S file is modified for not initializing global timer for
248 * OpenAMP application as it might be already in use by master CPU

253 * R5 deadlock for errata 780125

257 * for XOcm_Remap function

261 * kvn 21/11/15 Changed ADDR variable type from u32 to UINTPTR. This is
262 * required for MISRA-C:2012 Compliance.
263 * 5.4 pkp 23/11/15 Added attribute definitions for Xil_SetTlbAttributes API of Cortex-A9
264 * in cortexa9/xil_mmu.h

266 * 5.4 pkp 11/12/15 Modified common/xplatform_info.h to add #defines for silicon for
267 * checking the current executing platform
268 * 5.4 pkp 18/12/15 Modified cortexa53/32bit/gcc/xil-crt0.S and 64bit/gcc/xil-crt0.S

272 * 5.4 pkp 18/12/15 Modified cortexa53/32bit/gcc/translation_table.S and 64bit/gcc/
273 * translation_table.S to update the translation table according to proper
275 * 5.4 pkp 18/12/15 Modified cortexar5/mpu.c to initialize the MPU according to proper
277 * 5.4 pkp 05/01/16 Modified cortexa53/64bit/boot.S to set the reset vector register RVBAR
278 * equivalent to vector table base address
279 * 5.4 pkp 08/01/16 Modified cortexa9/gcc/Makefile to update the extra compiler flag
280 * as per the toolchain update

282 * for Cortex-A53 32bit mode

293 * cortexr5/xil-crt0.S to configure the TTC3 timer when present. Modified
294 * cortexr5/sleep.c, cortexr5/usleep.c to use TTC3 when present otherwise
295 * use set of assembly instructions to provide required delay to fix
297 * 5.4 asa 25/02/16 Made changes in xil-crt0.S for R5, A53 64 and 32 bit BSPs, to replace
298 * _exit with exit. We should not be directly calling _exit and should
299 * always use the library exit. This fixes the CR#937036.
300 * 5.4 pkp 25/02/16 Made change to cortexr5/gcc/boot.S to initialize the floating point
301 * registers, banked registers for various modes and enabled

318 * value and compare it with previous value to detect the overflow
320 * 5.4 pkp 03/24/16 Modified cortexr5/boot.S to reset the dbg_lpd_reset before enabling
321 * the fault log to avoid intervention for lock-step mode and cortexr5/
