Add support for VCore III SoCs found in Microsemi switches

Hello,

This series add the support of 2 SoCs: Ocelot and Luton from Microsemi. Both of them belongs to the same family Vcore III.

We found them on various advanced switches product.

The support for Ocelot already have been submit to Linux, but not yet the Luton support.

Besides this series 3 others patches are needed but they are driver related:
DW SPI: Allow to overload the management of the external CS
gpio: mscc-bitbang-spi: Add a simple gpio driver for bitbgang spi
pinctrl: mscc: Add gpio and pinctrl driver for MSCC MIPS SoCs (VcoreIII based)

They will be submitted separately.

Thanks,

Gregory

Gregory CLEMENT (6):
MIPS: move create_tlb() in an proper header: mipsregs.h
MSCC: add support for VCoreIII SoCs
MSCC: add board support for the VCoreIII based evaluation boards
MSCC: add device tree for Ocelot and Luton (boards and SoCs)
MSCC: add configuration for Ocelot and Luton based boards
MIPS: bootm: Add support for Vcore III linux kernel
