[SeaBIOS] Xen PV block device support in Seabios

[Shannon Zhao]

Hi,

I noticed there are some efforts to add Xen PV block device support in
Seabios in a GSoC project and there is a wiki page [1] for it. I found
some patches [2] to add Xenstore R/W support for Seabios. But I didn't
find the patches to add PV block device driver in Seabios.

If you know please tell me where I can find these patches. And I noticed
that the patches [2] and this GSoC project work didn't get applied to
Seabios eventually, is there any reason? Does it mean that there are
some difficulties to support Xen PV block device in Seabios?

Thanks in advance!
