[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 2/5] xen: Define EFI related stuff
Define EFI related stuff for Xen.
This patch is based on Jan Beulich and Tang Liang work.
v4 - suggestions/fixes:
- change some types from generic to Xen specific ones
(suggested by Stefano Stabellini),
- do some formating changes
(suggested by Jan Beulich).
