Hi,

The unicore32 port do not seem maintained for a long time now, there is no
upstream toolchain that can create unicore32 binaries and all the links to
prebuilt toolchains for unicore32 are dead. Even compilers that were
available are not supported by the kernel anymore.

Guenter Roeck says:

I have stopped building unicore32 images since v4.19 since there is no
available compiler that is still supported by the kernel. I am surprised
that support for it has not been removed from the kernel.

These patches remove support for unicre32 architecture as well as several
drives for devices available only on unicore32 machines.

The patches are also available at

https://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux.git/log/?h=rm-unicore
