Subject: [PATCH v2 15/19] powerpc: Remove CONFIG_PPC_BOOK3E_MMU
Date: Mon, 19 Sep 2022 19:01:39 +0200 [thread overview]
Message-ID: <c5549cd59a131204ff94ab909cad2e2dad4ddf2f.1663606876.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <828f6a64eeb51ce9abfa1d4e84c521a02fecebb8.1663606875.git.christophe.leroy@csgroup.eu>
CONFIG_PPC_BOOK3E_MMU is redundant with CONFIG_PPC_E500.
Remove it.
Also rename mmu-book3e.h to mmu-e500.h
