Subject: [PATCH v2 4/7] powerpc: Remove PowerPC 601
Date: Tue, 29 Sep 2020 06:09:21 +0000 (UTC)	[thread overview]
Message-ID: <00a6948d659e017f8ca63437d1384222c3aede57.1601359702.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <27951fa6c9a8f80724d1bc81a6117ac32343a55d.1601359702.git.christophe.leroy@csgroup.eu>

Powerpc 601 is 25 years old.

It is not selected by any defconfig.

It requires a lot of special handling as it deviates from the
standard 6xx.

Retire it.
