Subject: [PATCH v2] Revert "target/mips: Deprecate nanoMIPS ISA"
Date: Thu, 8 Apr 2021 17:01:42 +0000	[thread overview]
Message-ID: <VI1PR0302MB34862F042D9B1C72C7E4AD239C749@VI1PR0302MB3486.eurprd03.prod.outlook.com> (raw)

NanoMIPS ISA is supported again, since MediaTek is taking over
nanoMIPS toolchain development (confirmed at
https://www.spinics.net/linux/fedora/libvir/msg217107.html).

New release of the toolchain can be found at
(https://github.com/MediaTek-Labs/nanomips-gnu-toolchain/releases/tag/nanoMIPS-2021.02-01).

Reverting deprecation of nanoMIPS ISA requires following changes:
    MAINTAINERS: remove nanoMIPS ISA from orphaned ISAs
    deprecated.rst: remove nanoMIPS ISA from deprecated ISAs
