The Loongson-1A CPU is similar with Loongson-1B/1C, which is a 32-bit SoC. It is a cost-effective single chip system based on LS232 processor core, and is applicable to fields such as industrial control, and security applications. It implements the MIPS32 release 2 instruction set. They share the same PRID, so we rewrite them into PRID_REV_LOONGSON1ABC, and use their CPU macros to distinguish. Due to historic reasons, devicetree is not supported on Loongson1 platform now. Maybe it will have change in the future. Changes since v1: 1. According commit c908656a7531771ae7642990a7c5f3c7307bd612 (MIPS: Loongson: Naming style cleanup and rework) to fix the naming style. Changes since v2: 1. Remove __irq_set_handler_locked(). 2. Rebases on top of v4.5-rc5. Changes since v3: 1. Rename the Loongson-1 series's PRID name. 2. Rewite Loongson-1A's clk driver. 3. Rebases on top of v4.10-rc2. Changes since v4: 1. Fix comment's spelling error. Changes since v5: 1. Rebases on top of v4.11-rc3. Changes since v6: 1. Improve comment readability. 2. Rebases on top of v4.12-rc4. Changes since v7: 1. Rename Loongson1 clk driver's spinlock name.
