If you're REALLY interested in knowing everything about Compact Flash,
go here: http://www.compactflash.org/  You can download the spec, which
should help you sleep.

If you want to know how to interface Compact Flash to your Local Bus,
here's a good document.  I'm not intimately familiar with the 8360, but
unless Freescale has changed their LBC design, it should apply:

You shouldn't have to write your own driver for this.  I don't feel
totally comfortable giving you somebody else's code that isn't
necessarily finished, but since you could Google it yourself anyway,
here's a link to one that was put up for comment several months ago.  I
had no part in authoring it and have no idea where it stands regarding
inclusion in the kernel, so please treat it as experimental.  It will
require a bit of work on your part to understand how to specify platform
devices.
