* spi/spi-fsl-spi: Add support for Aeroflex Gaisler GRLIB cores normally ↵Andreas Larsson2013-04-071-1/+12
| | | | | | | | | | | | | | | | | | | | running on SPARC This adds support for the mostly register-compatible SPICTRL cores from the GRLIB VHDL IP core library from Aeroflex Gaisler. They are normally running on SPARC. A different entry in of_fsl_spi_match matches this core and indicates a different hardware type that is used to set up different function pointers and special cases. The GRLIB core operates in cpu mode. The number of bits per word might be limited. There might be native chipselects selected via a slave select register. These differences to the FSL type cores, if present, are indicated by a capabilities register. Other register and function differences exists but are not relevant to the driver.

* spi/spi-fsl-spi: Make driver usable in CPU mode outside of an FSL_SOC ↵Andreas Larsson2013-04-071-0/+61
environment This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and even an powerpc environment by moving CPM mode functionality to a separate file that is only compiled and linked in an FSL_SOC environment and adding some ifdefs to hide types and functions or provide alternatives. For devicetree probing a "clock-frequency" property is used for clock frequency instead of calls to FSL_SOC-specific functions.
