+ CONFIG_ARM_ERRATA_761320
If set, the workarounds for these ARM errata are applied early
during U-Boot startup. Note that these options force the
CONFIG_CMD_CDP * Cisco Discover Protocol support
CONFIG_CMD_MFSL * Microblaze FSL support
CONFIG_CMD_XIMG Load part of Multi Image
-
+ CONFIG_CMD_UUID * Generate random UUID or GUID string
EXAMPLE: If you want all functions except of network
support you can write:
this to the maximum filesize (in bytes) for the buffer.
Default is 4 MiB if undefined.
+ DFU_DEFAULT_POLL_TIMEOUT
+ Poll timeout [ms], is the timeout a device can send to the
+ host. The host must wait for this timeout before sending
+ a subsequent DFU_GET_STATUS request to the device.
+
+ DFU_MANIFEST_POLL_TIMEOUT
+ Poll timeout [ms], which the device sends to the host when
+ entering dfuMANIFEST state. Host waits this timeout, before
+ sending again an USB request to the device.

- Journaling Flash filesystem support:
CONFIG_JFFS2_NAND, CONFIG_JFFS2_NAND_OFF, CONFIG_JFFS2_NAND_SIZE,
CONFIG_JFFS2_NAND_DEV
If this option is set, then U-Boot will prevent the environment
variable "splashimage" from being set to a problematic address
- (see README.displaying-bmps and README.arm-unaligned-accesses).
+ (see README.displaying-bmps).
This option is useful for targets where, due to alignment
restrictions, an improperly aligned BMP image will cause a data
abort. If you think you will not have problems with unaligned
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.
Configuration Settings:
-----------------------
+- CONFIG_SYS_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
+ Optionally it can be defined to support 64-bit memory commands.
+
- CONFIG_SYS_LONGHELP: Defined when you want long help messages included;
undefine this when you're short of memory.

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.
-
- CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC (OMAP only)
This is set by OMAP boards for the max time that reset should
be asserted. See doc/README.omap-reset-time for details on how
- 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:
