How 8349mITX's compact flash is wired? If it is wired using 8 bit data bus line,
without another patch, data transfer can't be done.
Looking at logs Sam Sparks provided (without irq):
ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4)
it seems data transfer failed.
I have a 8 bit data trans

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

When I remove the interrupt definition from the DTS (to cause
irqpolling), the ata driver gets stuck in a loop displaying the
