[PATCH v2 0/8] MIPS: Loongson: Add the Loongson-1A processor support

[Binbin Zhou <zhoubb@lemote.com>]

The Loongson 1A is similar with Loongson 1B, which is a 32-bit SoC.
It implements the MIPS32 release 2 instruction set.

They share the same PRID, so we rewrite the PRID_REV_LOONGSON1B to
PRID_REV_LOONGSON1A_1B, and use their CPU macros to distinguish.

However, Loongson 1A has a bug that the pll register can't be read,
so we set the cpu clk in the inline command line.

The command line format is cpu_clk=osc_clk,cpu_mul, the osc_clk standby cpu clock
and the cpu_mul repect the clock multiplier.

For example, we use the command is cpu_clk=33333333,8

Changes since v1
----------------

According commit c908656a7531771ae7642990a7c5f3c7307bd612 
(MIPS: Loongson: Naming style cleanup and rework) to fix the naming style.

Binbin Zhou(8):
