Subject: [PATCH v2 11/19] powerpc: Change CONFIG_E500 to CONFIG_PPC_E500
Date:   Mon, 19 Sep 2022 19:01:35 +0200
Message-Id: <e63b22083c11c4300f4a82d3123a46e5fdd54fa6.1663606876.git.christophe.leroy@csgroup.eu>
In-Reply-To: <828f6a64eeb51ce9abfa1d4e84c521a02fecebb8.1663606875.git.christophe.leroy@csgroup.eu>
References: <828f6a64eeb51ce9abfa1d4e84c521a02fecebb8.1663606875.git.christophe.leroy@csgroup.eu>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

It will be used outside arch/powerpc, make it clear its a
powerpc configuration item.

And we already have CONFIG_PPC_E500MC, so that will make
it more consistant.
