+Subject: [PATCH] ARM: BCM5310X: activate erratas needed for SoC
+
+The BCM4708 I have, which is probably the first generation which got
+to the consumer market, is using a ARM Cortex-A9 rev r3p0 and a
+L2C-310 rev r3p2 L2 cache controller. There are 3 workarounds for known
+erratas in the Linux kernel which could be activated and will be in
+this patch. There are currently no workarounds which have to be
+activated for the L2C-310 rev r3p2 in Linux.
