Right, thanks.
Ultimately it's as simple as:
• Build SeaBIOS with CONFIG_CSM
• Drop the resulting Csm16.bin into OvmfPkg/Csm/Csm16/ in the EDK2 tree
• Build EDK2 with -DCSM_ENABLE
Someone else mailed me recently to say they'd copied the Csm packages
over from OvmfPkg to Quark and had Windows booting on Galileo boards.
Hm, I wonder if we should move the CSM support out of OVMF and into
somewhere more generic, since it really is generic and not platform-
specific?
