+Subject: [PATCH 1/7] MIPS: BCM63XX: remove duplicate spi register definitions
+
+BCM6338 and BCM6348, and BCM6358 and everything after that share the
+same register layout. To not have to redefine them for each new chip
+and keep the code size small, only use the definitions for the first
+chip with the certain layout.
