* 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:
