[SeaBIOS] DMI based quirks?

[Christian Gmeiner]

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/bach...

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=a...

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
