Hello,

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

Proposed patches fix some shortcomings when using multiboot2, like the
ignoring of the vga= parameter and forcefully switching the console to
the maximum supported resolution.

Thanks, Roger.

  multiboot2: parse vga= option when setting GOP mode
  multiboot2: do not set StdOut mode unconditionally
  cmdline: parse multiple instances of the vga option
