[PATCH v4 0/4] Support SiFive Composable cache driver

[Zong Li]

This patch set contains the SiFive composable cache support, and
uses this driver to enable the ways of ccache by overwriting the
enable_caches.

Changed in v4:
 - Use generic enable_caches(), rather than cache_init().
 - Rebase code base to v2021.10-rc3

Changed in v3:
 - Combine some patches
 - Drop the subdirectories of vendor in lib/
 - Rebase codebase

Changed in v2:
 - Refine the ccache driver by Sean's suggestions
 - Introduce a common interface for cache initialization

Zong Li (4):
  cache: add sifive composable cache driver
  riscv: lib: implement enable_caches for sifive cache
  board: sifive: use ccache driver instead of helper function
  riscv: lib: modify the indent
