Wolfgang Denk c786f427f9 Adjust filenames for USB update images on TRAB board.
During an automatic update via USB stick, U-Boot searches for
images with the name "firmware.img" and "kernel.img". This names
are now changed to "firmw_01.img" and "kernl_01.img". This is done,
to prevent updates of new boards (with the new macronics "c" step
flashes) with old, incompatible firmware or kernel versions.

vfd.c Bugfix in VFD routine on TRAB board. 2006-07-19 14:23:12 +02:00

The TRAB keyboard implementation is similar to that for LWMON and
R360MPI boards. The only difference concerns key naming. There are 4
keys on TRAB: 1, 2, 3, 4.

1) The "kbd" command provides information about the current state of
   the keys. For example,

	TRAB # kbd
	Keys: 1 0 1 0

   means that keys 1 and 3 are pressed. The keyboard status is also
   stored in the "keybd" environment variable. In this example we get

	keybd=1010

2) The "preboot" variable is set according to current environment
   settings and keys pressed. This is an example:

	TRAB # setenv magic_keys XY
	TRAB # setenv key_magicX 12
	TRAB # setenv key_cmdX echo ## Keys 1 + 2 pressed ##\;echo
	TRAB # setenv key_magicY 13
	TRAB # setenv key_cmdY echo ## Keys 1 + 3 pressed ##\;echo

   Here "magic_keys=XY" means that the "key_magicX" and "key_magicY"
   variables will be checked for a match. Each variable "key_magic*"
   defines a set of keys. In the our example, if keys 1 and 3 are
   pressed during reset, then "key_magicY" matches, so the "preboot"
   variable will be set to the contents of "key_cmdY":

	preboot=echo ## Keys 1 + 3 pressed ##;echo

3) The TRAB board has optional modem support. When a certain key
   combination is pressed on the keyboard at power-on, the firmware
   performs the necessary initialization of the modem and allows for
   dial-in. The key combination is specified in the
   "include/configs/trab.h" file. For example:

	#define        CONFIG_MODEM_KEY_MAGIC  "23"

   means that modem will be initialized if and only if both keys 2, 3
   are pressed. Note that the format of this string is similar to the
   format of "key_magic*" environment variables described above.
