[v2,0/7] x86: efi: Add a 64-bit coreboot payload

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 v2:
- Add a new patch to indicate 32/64-bit in bdinfo

  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: cbfs: Drop unwanted declaration
  x86: coreboot: Allow building an SPL image
  x86: Add an indication of 32/64-bit to bdinfo
  x86: Add a 64-bit coreboot build

When testing this series, it does not build on top of u-boot-x86/master.

arch/x86/cpu/built-in.o: In function `get_coreboot_info':
u-boot/arch/x86/cpu/coreboot/tables.c:228: undefined reference to
`locate_coreboot_table'
Segmentation fault (core dumped)
Makefile:1769: recipe for target 'u-boot' failed
make: *** [u-boot] Error 139
make: *** Deleting file 'u-boot'

Please take a look.
