From: Rick Chen <rick at andestech.com>
Add a v5l2 cache controller driver that is usually found on
Andes RISC-V ae350 platform. It will parse and configure the
cache settings (data & instruction prefetch, data & tag latency)
from the device tree blob.
Also implement L2 cache flush and disable before jump to linux.
The sequence will be preferred as below:
L1 flush -> L1 disable -> L2 flush -> L2 disable
Rick Chen (6):
dm: cache: add v5l2 cache controller driver
riscv: ae350: use the v5l2 driver to configure the cache
riscv: ae350: add imply v5l2 cache controller
riscv: cache: Flush L2 cache before jump to linux
riscv: dts: move out AE350 L2 node from cpus node
riscv: ax25: use CCTL to flush d-cache
