From 719f2ac49b6e893c1d6a88956e306d77a906d338 Mon Sep 17 00:00:00 2001 From: Emmanuel Vadot <manu@freebsd.org> Date: Fri, 4 May 2018 10:26:55 +0200 Subject: [PATCH] video: sunxi: de2: Reserve the fb region in the EFI memory map If compile with support for the efi loader we need to mark the pages allocated for the framebuffer as reserved so the kernel won't attempt to use them for other uses.
