[SeaBIOS] [PATCH 0/2] Fix reset issue with QEMU -machine q35

[Volker Rümelin]

This reset issue was reported on the QEMU issue tracker at
https://gitlab.com/qemu-project/qemu/-/issues/766

A reset with QEMU -machine q35 -accel tcg leads to a reset loop
and with -machine q35 -accel kvm the reset only works because
KVM ignores the read-only semantics of the C-F segments.

Details about the issue are in "reset: force standard PCI
configuration access".
