Hi all.
Would it be possible to add some DMI based quirks? I have a device and
in coreboot I have
some detection code for it:
http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/mainboard/bachmann/ot200/mainboard.c;h=0ea053aad0c9e085bbd8ea36f14210404881edb7;hb=HEAD
Now it takes quite some time to load Grub in PIO mode even the device
could use DMA.
For the linux kernel I have added this patch:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=abf8f2b877846573f0e6498883fe43f08be5696d
What would be the best solution in seabios to use PIO for broken devices and DMA
for the others? The biggest problem is that the device supports DMA
but due a missing
resister I breaks in DMA.
thanks
