Compact Flash on 8349mITX

[Jeff Borlin]

I have taken over this effort to get Compact Flash working on the 8349mITX
board and am running into these same issues.  I can get uBoot to list the
contents of a CF card, but am running into a couple problems through the
kernel.  There appears to be an IRQ problem and a general communication
problem with the CF card, possibly related.  Note that I am very new to
Linux so please don't assume obvious things are correct

I am using the latest from /linux/kernel/git/benh/powerpc.git, and created
my dtb from:  arch/powerpc/dts/mpc8349emitx.dts.  

Any ideas on what I could try or look into next with either issue?
