[U-Boot] [PATCH v4 5/9] armv8: ls2080a: Declare spin tables as reserved for efi loader

Alexander Graf agraf at suse.de
Tue Jun 21 01:07:15 CEST 2016


The efi loader code has its own memory map, so it needs to be aware where
the spin tables are located, to ensure that no code writes into those
regions.
