The old packages Coreboot*Pkgs will be removed. Which means now only QEMU/OVMF needs the Legacy8254 support. Laszlo, Now since QEMU/OVMF is the only consumer of the Legacy8254 driver, do you agree that the Legacy8254 is moved to OvmfPkg? Note: We agreed that Legacy8259 will be moved to OvmfPkg/Csm directory and that decision is not going to be changed by this new situation.
