Note that the NAND subsystem is full of unmaintained legacy drivers, so
every time we see someone who could help us get rid or update one of
them we have to take this opportunity.
Don't we rather insist to have a MAINTAINERS record for new code to
avoid (or delay at least) the fate of the legacy drivers?

Well, that's what we do for new drivers, but the xway driver has been
added in 2012 and the policy was not enforced at that time. BTW, that
goes for most of the legacy drivers in have in the NAND subsystems
(some of them even predate the git era).

To be clear, I just checked and there's no official maintainer for this
driver. Best option would be to Cc the original author and contributors
who proposed functional changes to the code, as well as the MIPS
maintainers (Xway is a MIPS platform).
A lot of the pre-acquisition code for lantiq was contributed by Hauke
Mehrtens and John Crispin. There was an intermediate generation of
MIPS SoCs with patches posted for review by Intel in 2018 (presumably
by the same organizatiob), but those were never resubmitted after v2
and never merged:

Thank you for reviewing our patches and your time...
The above patches for different SoC which is MIPS based, but whatever the patch is sent by me is Intel X86 ATOM based LGM SoC.

Vadivel
