Supported are USB Keyboards and USB Floppy drives
(TEAC FD-05PUB).
+- MMC Support:
+ The MMC controller on the Intel PXA is supported. To
+ enable this define CONFIG_MMC. The MMC can be
+ accessed from the boot prompt by mapping the device
+ to physical memory similar to flash. Command line is
+ enabled with CFG_CMD_MMC. The MMC driver also works with
+ the FAT fs. This is enabled with CFG_CMD_FAT.

+- Keyboard Support:
+ CONFIG_KEYBOARD
+
+ Define this to enable a custom keyboard support.
+ This simply calls drv_keyboard_init() which must be
+ defined in your board-specific files.
+ The only board using this so far is RBC823.
- LCD Support: CONFIG_LCD
Note:
- In the current implementation, the local variables
- space and global environment variables space are
- separated. Local variables are those you define by
- simply typing like `name=value'. To access a local
- variable later on, you have write `$name' or
- `${name}'; variable directly by typing say `$name' at
- the command prompt.

Global environment variables are those you use
setenv/printenv to work with. To run a command stored
the environment like the autoscript function or the

- CFG_MONITOR_LEN:
- Size of memory reserved for monitor code
+ Size of memory reserved for monitor code, used to
+ determine _at_compile_time_ (!) if the environment is
+ embedded within the U-Boot image, or in a separate
+ flash sector.
- CFG_MALLOC_LEN:
Size of DRAM reserved for malloc() use.
Define if the flash driver uses extra elements in the
common flash structure for storing flash geometry
+- CFG_RX_ETH_BUFFER:
+ Defines the number of ethernet receive buffers. On some
+ ethernet controllers it is recommended to set this value
+ to 8 or even higher (EEPRO100 or 405 EMAC), since all
+ buffers can be full shortly after enabling the interface
+ on high ethernet traffic.
+ Defaults to 4 if not defined.

Building the Software:
======================
GENIETV_config TQM823L_config PIP405_config
GEN860T_config EBONY_config FPS860L_config
ELPT860_config cmi_mpc5xx_config NETVIA_config
+ at91rm9200dk_config
Note: for some board special configuration names may exist; check if
additional information is available from the board vendor; for
setenv initrd_high 00c00000
+ If you set initrd_high to 0xFFFFFFFF, this is an
+ indication to U-Boot that all addresses are legal
+ for the Linux kernel, including addresses in flash
+ memory. In this case U-Boot will NOT COPY the
+ ramdisk at all. This may be useful to reduce the
+ boot time on your system, but requires that this
+ feature is supported by your Linux kernel.
+
ipaddr - IP address; needed for tftpboot command
loadaddr - Default load address for commands like "bootp",
only effect after the next boot (yes, that's just like Windoze :-).
+Command Line Parsing:
+=====================
+
+There are two different command line parsers available with U-Boot:
+the old "simple" one, and the much more pwerful "hush" shell:
+
+Old, simple command line parser:
+--------------------------------
+
+- supports environment variables (through setenv / saveenv commands)
+- several commands on one line, separated by ';'
+- variable substitution using "... $(name) ..." syntax
+- special characters ('$', ';') can be escaped by prefixing with '\',
+ for example:
+ setenv bootcmd bootm \$(address)
+- You can also escape text by enclosing in single apostrophes, for example:
+ setenv addip 'setenv bootargs $bootargs ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname::off'
+
+Hush shell:
+-----------
+
+- similar to Bourne shell, with control structures like
+ if...then...else...fi, for...do...done; while...do...done,
+ until...do...done, ...
+- supports environment ("global") variables (through setenv / saveenv
+ commands) and local shell variables (through standard shell syntax
+ "name=value"); only environment variables can be used with "run"
+ command
+
+General rules:
+--------------
+
+(1) If a command line (or an environment variable executed by a "run"
+ command) contains several commands separated by semicolon, and
+ one of these commands fails, then the remaining commands will be
+ executed anyway.
+
+(2) If you execute several variables with one call to run (i. e.
+ calling run with a list af variables as arguments), any failing
+ command will cause "run" to terminate, i. e. the remaining
+ variables are not executed.
+
