efi_loader: eliminate sandbox addresses
Do not use the sandbox's virtual address space for the internal structures of the memory map. This way we can eliminate a whole lot of unnecessary conversions. The only conversion remaining is the one when adding known memory. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
