Where to get help:
==================
boot. See the documentation file README.video for a
description of this variable.
+ CONFIG_VIDEO_VGA
+
+ Enable the VGA video / BIOS for x86. The alternative if you
+ are using coreboot is to use the coreboot frame buffer
+ driver.
+
+
- Keyboard Support:
CONFIG_KEYBOARD
HERMES, IP860, RPXlite, LWMON,
FLAGADM, TQM8260
+- Access to physical memory region (> 4GB)
+ Some basic support is provided for operations on memory not
+ normally accessible to U-Boot - e.g. some architectures
+ support access to more than 4GB of memory on 32-bit
+ machines using physical address extension or similar.
+ Define CONFIG_PHYSMEM to access this basic support, which
+ currently only supports clearing the memory.
+
- Error Recovery:
CONFIG_PANIC_HANG
-150 common/cmd_nand.c Incorrect FIT image format
151 common/cmd_nand.c FIT image format OK
+- FIT image support:
+ CONFIG_FIT
+ Enable support for the FIT uImage format.
+
+ CONFIG_FIT_BEST_MATCH
+ When no configuration is explicitly selected, default to the
+ one whose fdt's compatibility field best matches that of
+ U-Boot itself. A match is considered "best" if it matches the
+ most specific compatibility entry of U-Boot's fdt's root node.
+ The order of entries in the configuration's fdt is ignored.
+
- Standalone program support:
CONFIG_STANDALONE_LOAD_ADDR
Include standard software ECC in the SPL
CONFIG_SPL_NAND_SIMPLE
- Support for drivers/mtd/nand/libnand.o in SPL binary
+ Support for NAND boot using simple NAND drivers that
+ expose the cmd_ctrl() interface.
CONFIG_SYS_NAND_5_ADDR_CYCLE, CONFIG_SYS_NAND_PAGE_COUNT,
CONFIG_SYS_NAND_PAGE_SIZE, CONFIG_SYS_NAND_OOBSIZE,
CONFIG_SYS_NAND_ECCPOS, CONFIG_SYS_NAND_ECCSIZE,
CONFIG_SYS_NAND_ECCBYTES
Defines the size and behavior of the NAND that SPL uses
- to read U-Boot with CONFIG_SPL_NAND_SIMPLE
+ to read U-Boot
CONFIG_SYS_NAND_U_BOOT_OFFS
- Location in NAND for CONFIG_SPL_NAND_SIMPLE to read U-Boot
- from.
+ Location in NAND to read U-Boot from
+
+ CONFIG_SYS_NAND_U_BOOT_DST
+ Location in memory to load U-Boot to
+
+ CONFIG_SYS_NAND_U_BOOT_SIZE
+ Size of image to load
CONFIG_SYS_NAND_U_BOOT_START
- Location in memory for CONFIG_SPL_NAND_SIMPLE to load U-Boot
- to.
+ Entry point in loaded image to jump to
CONFIG_SYS_NAND_HW_ECC_OOBFIRST
Define this if you need to first read the OOB and then the
be used if available. These functions may be faster under some
conditions but may increase the binary size.
+- CONFIG_X86_NO_RESET_VECTOR
+ If defined, the x86 reset vector code is excluded. You will need
+ to do this when U-Boot is running from Coreboot.
+
+- CONFIG_X86_NO_REAL_MODE
+ If defined, x86 real mode code is omitted. This assumes a
+ 32-bit environment where such code is not needed. You will
+ need to do this when U-Boot is running from Coreboot.
