From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Unify the behaviour of the PCI ROM vs. SPI flash VBT
read codepaths, and relocate out the low level nuts details
from intel_bios.c into a new soc/intel_rom.c file.

v2: Sort out the drm_dbg() vs. drm_dbg_kms() mess
    Include terminating '\0' in vbt_signature[]
    Drop an unneccesry cast

Ville Syrjälä (6):
  drm/i915/bios: Use drm_dbg_kms() consistently
  drm/i915/bios: Add some size checks to SPI VBT read
  drm/i915/bios: Round PCI ROM VBT allocation to multiple of 4
  drm/i915/bios: Extract intel_spi_read16()
  drm/i915/bios: Extract vbt_signature[]
  drm/i915/bios: Extract soc/intel_rom.c
