[SeaBIOS] [PATCH 0/3] Use VGA Hooks to make Xen VGA passthrough work on certain devices

From: Julian Pidancet

The Intel gfx VGA option ROM on certain platforms requires the 155f50 BIOS function to be
implemented (even if it does nothing), to work properly. This series of patch allow
VGA passthrough on Xen to work on these platforms.

An example of these platform is the Dell Lattitude E6410 laptop, on which these patchs were
tested.

Julian Pidancet (3):
  vgahooks: Allow usage of VGA hooks in the Xen case
  vgahooks: Register 155f vga hooks for Xen Intel passthrough devices
  vgahooks: Create 155f50 hook.
