+ 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
allows for a "silent" boot where a splash screen is
loaded very quickly after power-on.
+ CONFIG_SPLASHIMAGE_GUARD
+
+ 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).
+ 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
+ accesses (for example because your toolchain prevents them)
+ there is no need to set this option.
+
CONFIG_SPLASH_SCREEN_ALIGN
If this option is set the splash image can be freely positioned
=> vertically centered image
at x = dspWidth - bmpWidth - 9
+ CONFIG_SPLASH_SCREEN_PREPARE
+
+ If this option is set then the board_splash_screen_prepare()
+ function, which must be defined in your code, is called as part
+ of the splash screen display sequence. It gives the board an
+ opportunity to prepare the splash image data before it is
+ processed and sent to the frame buffer by U-Boot.
+
- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
If this option is set, additionally to standard BMP
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:
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.
