-Subject: [PATCH 01/11] MIPS: BCM63XX: add USB host clock enable delay
-
-Knowledge of the clock setup delay should remain at the clock level (so
-it can be clock specific and CPU specific). Add the 100 milliseconds
-required clock delay for the USB host clock when it gets enabled.

+Subject: [PATCH 04/10] MIPS: bmips: change compile time checks to runtime
+ checks
+
+Allow building for all bmips cpus at the same time by changing ifdefs
+to checks for the cpu type, or adding appropriate checks to the
+assembly.
