1. I heard someone had the altcf working with the latest uClinux-dist.

2. I had displayed the IDE pin assignment using altcf core in CompactFlash wiki page.

.iord_n_from_the_cf_0 (dior),

.iordy_to_the_cf_0 (iordy),

.iowr_n_from_the_cf_0 (diow),

.reset_n_cf_from_the_cf_0 (reset)

Remove unused pins of altcf.

The key issue is the detect_n_to_the_cf_0 , which should be forced low for IDE.
