[PATCH 0/8] Support 64-bit U-Boot for Slim Bootloader

[aiden.park at intel.com]

From: Aiden Park <aiden.park at intel.com>

This patchset will build 64-bit U-Boot as a Slim Bootloader payload
and introduce a new X86_RUN_64BIT_ONLY to build pure 64-bit U-Boot
binary without SPL. In addition, this supports 64-bit kernel booting
from 64-bit U-Boot.

Aiden Park (8):
  x86: Add a new X86_RUN_64BIT_ONLY to Kconfig
  x86: start64: Add a hook at 64-bit entry
  x86: start64: Support HOB in 64-bit U-Boot
  x86: slimbootloader: Support 64-bit operation
  configs: slimbootloader: Add x86_64 slimbootloader config
  x86: Fix 64-bit compile warning
  x86: enable 64-bit kernel boot from 64-bit U-Boot
