+The CompactFlash(R) controller on the Korat board provides a hi-speed USB
+interface. This may be connected to either a dedicated port on the on-board
+USB controller, or to a USB port on the PowerPC 440EPx processor. The U-Boot
+environment variable "korat_usbcf" can be used to specify which of these two
+USB host ports is used for CompactFlash. The valid setting for the variable are
+the strings "pci" and "ppc". If the variable defined and set to "ppc", then the
+PowerPC USB port is used. In all other cases the on-board USB controller is
+used, but if "korat_usbcf" is defined but is set to a string other than the two
+valid options, a warning is also issued.
