From d37c2c231831d84f738fed22ca973a85622ae4d8 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Tue, 25 Dec 2018 02:52:52 +0100 Subject: Makefile.inc: Make sure the BIOS region is 64K aligned If a non aligned CONFIG_CBFS_SIZE is used the region RW_MRC_CACHE and CONSOLE could end up non aligned. Currently this is only possible if the user messes with CONFIG_CBFS_SIZE in menuconfig, but better be safe than sorry.
