John Crispin ec3eaeca91 spi/mips-lantiq: set SPI_MASTER_HALF_DUPLEX flag
Due to hardware limitations of the spi/flash frontend of the EBU we need to set
the SPI_MASTER_HALF_DUPLEX flag.

John Crispin 737a7c4380 spi/mips-lantiq: make use of spi_finalize_current_message
Rather than calling m->complete() directly we choose the sane way and call
spi_finalize_current_message instead.

Grant Likely fd4a319bc9 spi: Remove HOTPLUG section attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

Thomas Langer 6cd3c7e2b1 SPI: MIPS: lantiq: add FALCON spi driver
The external bus unit (EBU) found on the FALCON SoC has spi emulation that is
designed for serial flash access. This driver has only been tested with m25p80
type chips. The hardware has no support for other types of spi peripherals.
