-               Adding this option adds support for Xilinx SystemACE
-               chips attached via some sort of local bus. The address
-               of the chip must also be defined in the
-               CONFIG_SYS_SYSTEMACE_BASE macro. For example:
-
-               #define CONFIG_SYSTEMACE
-               #define CONFIG_SYS_SYSTEMACE_BASE 0xf0000000

-               When SystemACE support is added, the "ace" device type
-               becomes available to the fat commands, i.e. fatls.
