Subject: [PATCH v2 08/19] powerpc/cputable: Split cpu_specs[] for mpc85xx and e500mc
Date: Mon, 19 Sep 2022 19:01:32 +0200 [thread overview]
Message-ID: <553b901ea91e393df231103da4b018e9b251b0e9.1663606876.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <828f6a64eeb51ce9abfa1d4e84c521a02fecebb8.1663606875.git.christophe.leroy@csgroup.eu>
e500v1/v2 and e500mc are said to be mutually exclusive in Kconfig.
Split e500 cpu_specs[] and then restrict the non e500mc to PPC32
which is then 85xx.
