-Subject: [PATCH 153/153] MIPS: BCM47XX: Detect more then 128 MiB of RAM
- (HIGHMEM)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far BCM47XX can only detect amount of HIGHMEM. It still requires
-adding (registering) and well-testing before enabling by default.
