Message-Id: <c891ccbf2dfebf588e236d1ce1bfe66ac04d301d.1662658653.git.christophe.leroy@csgroup.eu>

Subject: [PATCH v1 11/19] powerpc: Change CONFIG_E500 to CONFIG_PPC_E500
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.
Signed-off-by: Christophe Leroy <christophe.leroy@...roup.eu>
