- * The Xilinx SystemACE chip support is activated by defining
- * CONFIG_SYSTEMACE to turn on support, and CFG_SYSTEMACE_BASE
- * to set the base address of the device. This code currently
- * assumes that the chip is connected via a byte-wide bus.
- *
- * The CONFIG_SYSTEMACE also adds to fat support the device class
- * "ace" that allows the user to execute "fatls ace 0" and the
- * like. This works by making the systemace_get_dev function
- * available to cmd_fat.c:get_dev and filling in a block device
- * description that has all the bits needed for FAT support to
- * read sectors.
- *
- * According to Xilinx technical support, before accessing the
- * SystemACE CF you need to set the following control bits:
- * 	FORCECFGMODE : 1
- * 	CFGMODE : 0
- * 	CFGSTART : 0
