* Patch by Martin Krause, 09 Oct 2003:

Fixes for TRAB board
  - /board/trab/rs485.c: correct baudrate
  - /board/trab/cmd_trab.c: bug fix for problem with timer overflow in
    udelay(); fix some timing problems with adc controller
  - /board/trab/trab_fkt.c: add new commands: gain, eeprom and power;
    modify commands: touch and buzzer

* Disable CONFIG_SUPPORT_VFAT when used with CONFIG_AUTO_UPDATE
  (quick & dirty workaround for rogue pointer problem in get_vfatname());
  Use direct function calls for auto_update instead of hush commands
