Until commit "arch/Config.in.sh: fixup MMU selection" in this series, SH2A could either be used with BR2_USE_MMU disabled or BR2_USE_MMU enabled. The later made absolutely no sense, since SH2A does not have a MMU: MMU support was introduced starting from SH3 according to https://en.wikipedia.org/wiki/SuperH#SH-3 Also, since commit22d5501e03("arch: tidy up binary formats config"), which was merged in Buildroot 2015.05, the architecture tuple used when BR2_sh2a=y and BR2_USE_MMU disabled is sh2a-buildroot-uclinux-uclibc, and this was already unsupported back in the days of Buildroot 2015.08 and binutils 2.24, causing the build to fail with: *** BFD does not support target sh2a-buildroot-uclinux-uclibc. just like it fails to build today with recent version of binutils. So, this has been broken since 2015.08, and nobody complained. SH2A is seldom used, so it's time to kill it. It is worth mentioning that there had been an attempt at resurrecting SH2 support around 2015 (see https://lwn.net/Articles/647636/) as part of the J2 core. This effort led to the addition of FDPIC support for SH2A in the musl C library (and therefore proper ELF binaries, with shared libraries), but that was never supported in Buildroot. Now that the J2 project is essentially dead, there is no reason to bother with this.

This directory contains various useful scripts and tools for working
with Buildroot. You need not add this directory in your PATH to use
any of those tools, but you may do so if you want.
brmake
a script that can be run instead of make, that prepends the date in
front of each line, redirects all of the build output to a file
("'br.log' in the current directory), and just outputs the Buildroot
messages (those lines starting with >>>) on stdout.
Do not run this script for interactive configuration (e.g. menuconfig)
or on an unconfigured directory. The output is redirected so you will see
nothing.
check-package
a script that checks the coding style of a package's Config.in and
.mk files, and also tests them for various types of typoes.
genrandconfig
a script that generates a random configuration, used by the autobuilders
(http://autobuild.buildroot.org). It selects a random toolchain from
support/config-fragments/autobuild and randomly selects packages to build.
get-developpers
a script to return the list of people interested in a specific part
of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as
input, a package name or and architecture name.
scancpan
a script to create a Buildroot package by scanning a CPAN module
description.
scanpypi
a script to create a Buildroot package by scanning a PyPI package
description.
size-stats-compare
a script to compare the rootfs size between two different Buildroot
configurations. This can be used to identify the size impact of
a specific option, of a set of specific options, or of an update
to a newer Buildroot version...
test-pkg
a script that tests a specific package against a set of various
toolchains, with the goal to detect toolchain-related dependencies
(wchar, threads...)
