Hi Linus,

The following changes since commit 9ebcfadb0610322ac537dd7aa5d9cbc2b2894c68:

Linux 5.8-rc3 (2020-06-28 15:00:24 -0700)

are available in the Git repository at:

https://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux.git/ tags/rm-unicore32

MAINTAINERS: remove "PKUNITY SOC DRIVERS" entry (2020-07-01 12:11:02 +0300)

----------------------------------------------------------------

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.

However, it's worth pointing out two things:

- Guan Xuetao is still listed as maintainer and asked for the port to be
kept around the last time Arnd suggested removing it two years ago. He
promised that there would be compiler sources (presumably llvm), but has
not made those available since.

- https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
released in 2016, with patches dated early 2019. These patches mainly
restore a syscall ABI that was never part of mainline Linux but apparently
used in production. qemu-2.8 removed support for that ABI and newer kernels
(4.19+) can no longer be built with the old toolchain, so apparently
there will not be any future updates to that git tree.
