-Subject: [PATCH] mips: bmips: enable RAC on BMIPS4350
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The data RAC is left disabled by the bootloader in some SoCs, at least in
-the core it boots from.
-Enabling this feature increases the performance up to +30% depending on the
-task.
