From fb37409a01b011a664347702f44dbf13fa7c7486 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 10 Jun 2020 09:45:20 +0300 Subject: arch: remove unicore32 port 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. Remove unicore32 port.
