Subject: [Buildroot] [PATCH 1/5] toolchain/toolchain-external: drop Synopsys ARC toolchain
Date: Sat,  8 Aug 2026 17:27:47 +0200	[thread overview]
Message-ID: <20260808152753.1278414-1-thomas.petazzoni@bootlin.com> (raw)

This toolchain is from 2024.06 and has not been updated since then. It
was marked in commit 11a8cdd2bbbd0ef4adf600e4792d75f6f2122ec8 in
January 2025.

A warning was sent to Synopsys ARC people in December 2025, and
despite a reply that some effort would be made [1], no contributions
were actually done. Also, Alexey Brodkin is no longer at
Synopsys. Time to remove Synopsys ARC specific toolchain and toolchain
components.
