-Subject: [PATCH 11/63] MIPS: BCM63XX: add stub to register the SPI platform driver
-
-This patch adds the necessary stub to register the SPI platform driver.
-Since the registers are shuffled between the 4 BCM63xx CPUs supported by
-this SPI driver we also need to generate the internal register layout and
-export this layout for the driver to use it properly.
