In linux kernel since version 2.6.12  
Compact Flash is a small, removable mass storage device introduced
in 1994 originally as a PCMCIA device. If you say `Y' here, you
compile in support for Compact Flash devices directly connected to
a SuperH processor. A Compact Flash FAQ is available at
<http://www.compactflash.org/faqs/faq.htm>.

If your board has "Directly Connected" CompactFlash at area 5 or 6,
you may want to enable this option. Then, you can use CF as
primary IDE drive (only tested for SanDisk).

If in doubt, select 'N'.
