mb/emulation/qemu-i440fx|q35: Switch to C_ENVIRONMENT_BOOTBLOCK
Useful for testing stuff in C_ENVIRONMENT_BOOTBLOCK, like VBOOT with separate verstage. Changes: * Use symbols to set up CAR and STACK * Zero CAR area * Move BIST failure checking to cpu folder * Rename functions where necessary Tested: * qemu-2.11.2 machine pc * qemu-2.11.2 machine q35 Test result: * BIST error reporting is still working. * Console starts in bootblock * SeaBios 1.11.2 as payload is still working Change-Id: Ibf341002c36d868b9b44c8b37381fa78ae5c4381 Signed-off-by: Patrick Rudolph <siro@das-labor.org> Reviewed-on: https://review.coreboot.org/29578 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
