We are running with the caches disabled when mctl_mem_matches gets called, but the cpu's write buffer is still there and can still get in the way, add a memory barrier to fix this. This avoids mctl_mem_matches always returning false in some cases, which was resulting in: U-Boot SPL 2015.07 (Apr 14 2016 - 18:47:26) DRAM: 1024 MiB U-Boot 2015.07 (Apr 14 2016 - 18:47:26 +0200) Allwinner Technology CPU: Allwinner A23 (SUN8I) DRAM: 512 MiB Where 512 MiB is the right amount, but the DRAM controller would be initialized for 1024 MiB.
