Hello Ralf,
2011/11/21 Florian Fainelli <florian@xxxxxxxxxxx>:
> 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.

There is a typo here, I will resubmit a version 2 of the patchset.
