* Modify KUP4X board configuration to use SL811 driver for USB memory

  sticks (including FAT / VFAT filesystem support)

* Add SL811 Host Controller Interface driver for USB

* Add CFG_I2C_EEPROM_ADDR_OVERFLOW desription to README

* Patch by Pantelis Antoniou, 19 Apr 2004:
  Allow to use shell style syntax (i. e. ${var} ) with standard parser.
  Minor patches for Intracom boards.

* Patch by Christian Pell, 19 Apr 2004:
