From ae903c56c112f463c964d85d4cbf37702aa5c67c Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 22 Jun 2018 00:53:44 +0100 Subject: [PATCH] allwinner: Don't map boot ROM There is nothing we need from the BootROM area, so we also don't need to map it in EL3. Remove the mapping and reduce the number of MMAP regions by one.
