[Qemu-devel] [PATCH] add missing firmware configuration channel numbers to BIOS

[Andre Przywara <andre.przywara@amd.com>]

Hi,

although we currently don't use firmware config channel
numbers higher than '0x02' in the PC-BIOS, add the channel
names to the BIOS source to mark already used entries.
This will make picking new number easier in the future.

Regards,
Andre.
