[PATCH v2 00/10] cache operation cleanups for Andes AE350 platform

This patchset is intended to enable L2-cache in U-boot SPL, along with cache operations cleanup for AE350 platforms.
Changes v1 -> v2: - Drop plicsw related patch - Include RB tags from Rick and Leo
The patchset is based on commit: a209c3e6b48cf042d0220245a2d1636f74389c17

The L2C configuration register has MAP field to indicate its version is v0 (Gen1) or v1 (Gen2) L2-cache. This patch makes the driver compatible with both memory-mapped scheme.

As the OpenSBI v1.2 does not enable the cache [0], we enable the i/d-cache in harts_early_init() and do not disable in cleanup_before_linux(). This patch also simplifies the logic and moves the CSR encoding to include/asm/arch-andes/csr.h.

To reduce the code size, CONFIG_V5L2_CACHE was disabled since commit: ca06444aac2c643db3a3f2eb37afc60fae15177e
Turing on does not significantly increase the size of u-boot-spl.bin, so we enable it by default to improve performance.
