  soc: sifive: l2 cache: Mark l2_get_priv_group as static (2020-05-28 15:57:49 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.8 Merge Window, Part 1

* The remainder of the code necessary to support the Kendryte K210.
    * Support for building device trees into the kernel, as the K210 doesn't
      have a bootloader that provides one.
    * A K210 device tree and the associated defconfig update.
    * Support for skipping PMP initialization on systems that trap on PMP
      accesses rather than treating them as WARL.
* Support for KGDB.
* Improvements to text patching.
* Some cleanups to the SiFive L2 cache driver.

I may have a second part, but I wanted to get this out earlier rather than
later as they've been ready to go for a while now.
