- depends on SOLUTION_ENGINE
- ---help---
- 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'.

- If your board has "Directly Connected" CompactFlash, You should
- select the area where your CF is connected to.

- - "Area6" if it is connected to Area 6 (0x18000000)
