Hello,

The following series contains some fixes and improvements related to
graphics usage when booting Xen.

Proposed patches fix some shortcomings when using multiboot2, mostly the
ignoring of the console=vga (or lack of) and the vga=gfx- parameters.
It also switches default Xen behaviour from trying to reuse the
currently set GOP mode instead of attempting to set the maximum
supported resolution.

Thanks, Roger.

  efi: try to use the currently set GOP mode
  multiboot2: parse console= and vga= options when setting GOP mode
  multiboot2: do not set StdOut mode unconditionally
