+ CONFIG_ARM_ERRATA_716044
+ CONFIG_ARM_ERRATA_742230
+ CONFIG_ARM_ERRATA_743622
+ CONFIG_ARM_ERRATA_751472
+
+ If set, the workarounds for these ARM errata are applied early
+ during U-Boot startup. Note that these options force the
+ workarounds to be applied; no CPU-type/version detection
+ exists, unlike the similar options in the Linux kernel. Do not
+ set these options unless they apply!

- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
boot loader that has already initialized the UART. Define this
variable to flush the UART at init time.
- CONFIG_SYS_NS16550_BROKEN_TEMT
-
- 16550 UART set the Transmitter Empty (TEMT) Bit when all output
- has finished and the transmitter is totally empty. U-Boot waits
- for this bit to be set to initialize the serial console. On some
- broken platforms this bit is not set in SPL making U-Boot to
- hang while waiting for TEMT. Define this option to avoid it.
-
- Console Interface:
Depending on board, define exactly one serial port
(requires CONFIG_CMD_MEMORY and CONFIG_MD5)
CONFIG_CMD_MEMINFO * Display detailed memory information
CONFIG_CMD_MEMORY md, mm, nm, mw, cp, cmp, crc, base,
- loop, loopw, mtest
+ loop, loopw
+ CONFIG_CMD_MEMTEST mtest
CONFIG_CMD_MISC Misc functions like sleep etc
CONFIG_CMD_MMC * MMC memory mapped support
CONFIG_CMD_MII * MII utility commands
Support for lib/libgeneric.o in SPL binary
CONFIG_SPL_PAD_TO
- Linker address to which the SPL should be padded before
- appending the SPL payload.
+ Image offset to which the SPL should be padded before appending
+ the SPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL
+ payload without any padding, or >= CONFIG_SPL_MAX_SIZE.
CONFIG_SPL_TARGET
Final target image containing SPL and payload. Some SPLs
If defined, don't allow the -f switch to env set override variable
access flags.
+- CONFIG_SYS_GENERIC_BOARD
+ This selects the architecture-generic board system instead of the
+ architecture-specific board files. It is intended to move boards
+ to this new framework over time. Defining this will disable the
+ arch/foo/lib/board.c file and use common/board_f.c and
+ common/board_r.c instead. To use this option your architecture
+ must support it (i.e. must define __HAVE_ARCH_GENERIC_BOARD in
+ its config.mk file). If you find problems enabling this option on
+ your board please report the problem and send patches!
+
+- CONFIG_SYS_SYM_OFFSETS
+ This is set by architectures that use offsets for link symbols
+ instead of absolute values. So bss_start is obtained using an
+ offset _bss_start_ofs from CONFIG_SYS_TEXT_BASE, rather than
+ directly. You should not need to touch this setting.
+
+
The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
- CONFIG_SYS_SRIOn_MEM_SIZE:
Size of SRIO port 'n' memory region
-- CONFIG_SYS_NDFC_16
- Defined to tell the NDFC that the NAND chip is using a
- 16 bit bus.
+- CONFIG_SYS_NAND_BUSWIDTH_16BIT
+ Defined to tell the NAND controller that the NAND chip is using
+ a 16 bit bus.
+ Not all NAND drivers use this symbol.
+ Example of drivers that use it:
+ - drivers/mtd/nand/ndfc.c
+ - drivers/mtd/nand/mxc_nand.c
- CONFIG_SYS_NDFC_EBC0_CFG
Sets the EBC0_CFG register for the NDFC. If not defined
If defined, the x86 reset vector code is included. This is not
needed when U-Boot is running from Coreboot.
+- CONFIG_SYS_MPUCLK
+ Defines the MPU clock speed (in MHz).
+
+ NOTE : currently only supported on AM335x platforms.
