[PATCH 1/5] mips: PMC MSP71xx core platform
Patch to add core platform support for the PMC-Sierra
MSP71xx devices.
These 5 patches along with the previously posted serial patch
will boot the PMC-Sierra MSP7120 Residential Gateway board.

+ * Notes:
+ * 1) The SPI registers are split into two blocks, one offset from the
+ * MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
+ * 0x68. The SPI driver definitions for the register must be aware
+ * of this.
+ * 2) The block copy engine register are divided into two regions, one
+ * for the control/configuration of the engine proper and one for the
+ * values of the descriptors used in the copy process. These have
+ * different base defines (CTRL_BASE vs DESC_BASE)
+ * 3) These constants are for physical addresses which means that they
+ * work correctly with "ioremap" and friends. This means that device
+ * drivers will need to remap these addresses using ioremap and perhaps
+ * the readw/writew macros. Or they could use the regptr() macro defined
+ * below, but the readw/writew calls are the correct thing.
+ * 4) The UARTs have an additional status register offset from the base
+ * address. This register isn't used in the standard 8250 driver but
+ * may be used in other software. Consult the hardware datasheet for
+ * offset details.
+ * 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ * start at an offset of 0x84 from the base address but the block of
+ * registers before this is reserved for the security engine. The driver
+ * will have to be aware of this but it makes the register definitions
+ * line up better with the documentation.
