From: Arnd Bergmann <arnd@arndb.de>

This platform is the oldest still supported machine, dating back
to the original 1994 ARM610 version.  The only currently supported
configuration uses an ARMv4 StrongARM but still requires building
for ARMv3 because of the board design not supporting 16-bit
data access.

ARMv3 support has been removed in gcc-9, and the gcc-8 release
is already old but still supported for building the kernel.

The only set of machines that lacks support for 16-bit load/store
instructions (Alpha EV5 and older) was recently removed from
the kernel.

Since there is little hope of this being maintainable much
longer, plan to remove it in early 2025 while it is still expected
to mostly work.
