ARM based boards:
-----------------
SIU Watchdog feature is enabled in the SYPCR
register.
+- U-Boot Version:
+ CONFIG_VERSION_VARIABLE
+ If this variable is defined, an environment variable
+ named "ver" is created by U-Boot showing the U-Boot
+ version as printed by the "version" command.
+ This variable is readonly.
+
- Real-Time Clock:
When CFG_CMD_DATE is selected, the type of the RTC
16,7 Mill (24bit) 315 318 31b
(i.e. setenv videomode 317; saveenv; reset;)
- CONFIG_VIDEO_SED13806
+ CONFIG_VIDEO_SED13806
Enable Epson SED13806 driver. This driver supports 8bpp
and 16bpp modes defined by CONFIG_VIDEO_SED13806_8BPP
or CONFIG_VIDEO_SED13806_16BPP
Normally display is black on white background; define
CFG_WHITE_ON_BLACK to get it inverted.
+- Spash Screen Support: CONFIG_SPLASH_SCREEN
+
+ If this option is set, the environment is checked for
+ a variable "splashimage". If found, the usual display
+ of logo, copyright and system information on the LCD
+ is supressed and the BMP image at the address
+ specified in "splashimage" is loaded instead. The
+ console is redirected to the "nulldev", too. This
+ allows for a "silent" boot where a splash screen is
+ loaded very quickly after power-on.
+

- Ethernet address:
CONFIG_ETHADDR
CONFIG_ETH2ADDR
These settings describe a second storage area used to hold
a redundand copy of the environment data, so that there is
- a valid backup copy in case there is a power failur during

a "saveenv" operation.

+ If set to "no", a standalone image passed to the
+ "bootm" command will be copied to the load address
+ (and eventually uncompressed), but NOT be started.
+ This can be used to load and uncompress arbitrary
+ data.

initrd_high - restrict positioning of initrd images:
If this variable is not set, initrd images will be
copied to the highest possible address in RAM; this
once they have been set once.

Please note that changes to some configuration parameters may take
only effect after the next boot (yes, that's just like Windoze :-).
to boot over the network using BOOTP etc., where the boot
server provides just a single image file, but you want to get
for instance an OS kernel and a RAMDisk image.

"Multi-File Images" start with a list of image sizes, each
image size (in bytes) specified by an "uint32_t" in network
byte order. This list is terminated by an "(uint32_t)0".
Immediately after the terminating 0 follow the images, one by
one, all aligned on "uint32_t" boundaries (size rounded up to
a multiple of 4 bytes).
-
+
"Firmware Images" are binary images containing firmware (like
U-Boot or FPGA images) which usually will be programmed to
flash memory.
-
+
"Script files" are command sequences that will be executed by
U-Boot's command interpreter; this feature is especially
useful when you configure U-Boot to use a real shell (hush)
