+Sandbox Environment:
+--------------------
+
+U-Boot can be built natively to run on a Linux host using the 'sandbox'
+board. This allows feature development which is not board- or architecture-
+specific to be undertaken on a native platform. The sandbox is also used to
+run some of U-Boot's tests.
+
+See board/sandbox/sandbox/README.sandbox for more details.
+
+
Configuration Options:
----------------------
supported, core will start to execute uboot when wakes up.
- Generic CPU options:
+ CONFIG_SYS_GENERIC_GLOBAL_DATA
+ Defines global data is initialized in generic board board_init_f().
+ If this macro is defined, global data is created and cleared in
+ generic board board_init_f(). Without this macro, architecture/board
+ should initialize global data before calling board_init_f().
+
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
Defines the endianess of the CPU. Implementation of those
boot loader that has already initialized the UART. Define this
variable to flush the UART at init time.
+ CONFIG_SERIAL_HW_FLOW_CONTROL
+
+ Define this variable to enable hw flow control in serial driver.
+ Current user of this option is drivers/serial/nsl16550.c driver
- Console Interface:
Depending on board, define exactly one serial port
CONFIG_SH_MMCIF_CLK
Define the clock frequency for MMCIF
+ CONFIG_GENERIC_MMC
+ Enable the generic MMC driver
+
+ CONFIG_SUPPORT_EMMC_BOOT
+ Enable some additional features of the eMMC boot partitions.
+
+ CONFIG_SUPPORT_EMMC_RPMB
+ Enable the commands for reading, writing and programming the
+ key for the Replay Protection Memory Block partition in eMMC.
+
- USB Device Firmware Update (DFU) class support:
CONFIG_DFU_FUNCTION
This enables the USB portion of the DFU USB class
Specify the number of FPGA devices to support.
+ CONFIG_CMD_FPGA_LOADMK
+
+ Enable support for fpga loadmk command
+
+ CONFIG_CMD_FPGA_LOADP
+
+ Enable support for fpga loadp command - load partial bitstream
+
+ CONFIG_CMD_FPGA_LOADBP
+
+ Enable support for fpga loadbp command - load partial bitstream
+ (Xilinx only)
+
CONFIG_SYS_FPGA_PROG_FEEDBACK
Enable printing of hash marks during FPGA configuration.
supports MMC, NAND and YMODEM loading of U-Boot and NAND
NAND loading of the Linux Kernel.
+ CONFIG_SPL_OS_BOOT
+ Enable booting directly to an OS from SPL.
+ See also: doc/README.falcon
+
CONFIG_SPL_DISPLAY_PRINT
For ARM, enable an optional function to print more information
about the running system.
Support for NAND boot using simple NAND drivers that
expose the cmd_ctrl() interface.
+ CONFIG_SPL_MTD_SUPPORT
+ Support for the MTD subsystem within SPL. Useful for
+ environment on NAND support within SPL.
+
CONFIG_SPL_MPC8XXX_INIT_DDR_SUPPORT
Set for the SPL on PPC mpc8xxx targets, support for
drivers/ddr/fsl/libddr.o in SPL binary.
- CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC:
Enables the RTC32K OSC on AM33xx based plattforms
+- CONFIG_SYS_NAND_NO_SUBPAGE_WRITE
+ Option to disable subpage write in NAND driver
+ driver that uses this:
+ drivers/mtd/nand/davinci_nand.c
+
Freescale QE/FMAN Firmware Support:
