This series creates a new 64-bit 'coreboot64' build which can be launched from coreboot. It uses SPL to effect the jump to 64-bit mode.
This was done in an attempt to get the Ubuntu FirmwareTestSuite[1] working. Unfortunately the latest version shows a splash screen and hangs, perhaps due to some missing EFI support.

Changes in v3: - Add new patch to make coreboot detection work in 64-bit code - Show bit width for all archs, use sizeof(void *)
Changes in v2: - Add a new patch to indicate 32/64-bit in bdinfo
Simon Glass (7): x86: Move coreboot-table detection to common 32/64-bit code x86: Allow building an SPL image for coreboot x86: Move work-around out of cpu_jump_to_64bit_uboot() x86: Update SPL for coreboot x86: coreboot: Allow building an SPL image x86: Add an indication of 32/64-bit to bdinfo x86: Add a 64-bit coreboot build
