Subject: [PATCH 00/13] MIPS: Convert Ingenic to a generic board

Hi Thomas & list,

Here is a set of patches for 5.10 (no rush) to move Ingenic support from
arch/mips/jz4740/ to arch/mips/generic/.

There are some Kconfig changes that I think should be reviewed in detail
to avoid breakages elsewhere. The idea behind these changes is to allow
the Ingenic "generic" code to be built in a non-generic kernel, since
generic kernels bring lots of dependencies which result in a +7% size
increase.

Support for booting the generic kernel with a built-in and/or appended
devicetree, as well as support for compressed (vmlinuz) kernels, has
been added as well.

Cheers,
-Paul
