[PATCH 0/8] MIPS: Loongson: Add basic Loongson-1A CPU support

[Binbin Zhou]

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

[PATCH 3/8] MIPS: Loongson: Add platform devices for Loongson-1A/1B

[Binbin Zhou]

Added basic platform devices for Loongson 1A, including serial port,
ethernet, AHCI, USB, RTC, SPI and so on.

Most of the devices are shared with Loongson 1B, like serial port,
ethernet, USB and so on.
Specially, something like AHCI is only used in Loonson 1A.

[PATCH 5/8] MIPS: Loongson-1A: Workaround for pll register can't be read

[Binbin Zhou]

This is Loongson 1A's 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

[PATCH 6/8] MIPS: Loongson-1A: Add IRQ type setting support

[Binbin Zhou]

Loongson 1A's INT controller support two different interrupt trigger mode:
level trigger and edge trigger.

Whether the INT controller stores the external interrupts is
the difference between them.
The edge trigger should do this, and operate INT_CLR register
to clear the CPU interrupt state.
