Hi,

This patch expands shadow memory of guest BIOS.
Currently the shadow memory is 0xc0000 - 0xdffff.
It is used by VGA, gPXE, option ROM, but the size of these ROMs is
around 40k->64k, so the area is not enough.

I updated the previous patch.
http://lists.xensource.com/archives/html/xen-devel/2008-12/msg01117.html

I separate it into 2 parts.
[1/2] replace e820 from 0xe0000 to oxeb000 (using E820_PHYSICAL_ADDRESS macro).
[2/2] expand shadow mem from 0xc0000-0xdffff to 0xc0000-0xe8fff.

Best Regards,

Akio Takebe
