Date: Thu, 13 Aug 2020 16:36:36 +0000 (UTC) From: Christophe Leroy <christophe.leroy@...roup.eu> To: Benjamin Herrenschmidt <benh@...nel.crashing.org>, Paul Mackerras <paulus@...ba.org>, Michael Ellerman <mpe@...erman.id.au> Cc: linux-kernel@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org Subject: [PATCH 5/9] powerpc: Remove PowerPC 601 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.
