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
