Subject: [PATCH 0/9] MIPS: CI20: Add WiFi / Bluetooth support

Hi,

Here's a set of patches to add support for the WiFi / Bluetooth chip on
the CI20.

WiFi works pretty well, provided it is used with the latest firmware
provided by linux-firmware. Bluetooth does not work very well here, as
I cannot get my wireless keyboard to pair; but it does detect it, and it
does see they key presses when I type the pairing code.

I only tested with a somewhat recent (~2022) Buildroot-based userspace.
I enabled WEXT compatibility because the CI20 is typically used with a
very old userspace, but I did not try to use it with old tools like
ifconfig/iwconfig.

Cheers,
-Paul
