Hi Tim,
I finally got a chance to try out your patches on my lite5200 board.
Unfortunately, I wasn't able to get it to work easily. I'm very early
in the debugging this issue, but I thought I'd send you my results in
case you've seen it before. I've tried this with both an STEC 1GB CF
and a Transcend Ultra industrial 1GB CF card.
When the patch is enabled, Linux boots to the point of probing the ATA
bus. The first attempt to probe uses UDMA/33 which ends in a timeout.
Second attempt limits it to UDMA/25 which also times out. Third
attempt falls back to PIO4 mode which then succeeds and the boot
process continues. I haven't dug into the details of MPC5200 UDMA
support yet, but I'd like to know if you have any ideas.
Cheers,
g.
