Xen devel - Nov 2013 - Re: [edk2] [PATCH RFC 0/7] OvmfPkg: make OVMF fully working with Xen

framebuffer address is NULL.

These modules would need to move to PcAtChipsetPkg in the non-hack version.

Can you copy the E820 structs from IntelFrameworkModulePkg/Csm/
LegacyBiosDxe/LegacyBiosInterface.h instead?

A quick glance makes me think the memmap stuff could tweaked, but I''ll
wait until it seems like this actually could work before I look at
this too close. :)
