Subject: [PATCH v3 00/15] MIPS: Convert Ingenic to a generic board v3

Hi Thomas, list,

Here's a V3 of my patchset that updates the old jz4740 platform code to
work with the generic MIPS board code base.

Noteworthy changes since V2:
- Patch [01/15] is a fix to the LB60's defconfig, which expected a
  symbol to be the default value of an enum, but the default changed in
  kernel 5.7.

- Patch [11/15] has been modified to address the issue with
  cpu-feature-overrides.h being dropped. Now, The Ingenic-specific
  version of the file will be used when building a Ingenic-only kernel,
  otherwise the generic dummy one will be used.

- Patch [13/15] is new, instead of doing code removal + rename in one
  patch in v2, we now do code removal in patch [12/15] and rename in
  [13/15]. It makes more sense to split since we have more files/folders
  (as we keep the cpu-feature-overrides.h header around).

Cheers,
-Paul
