Subject: [PATCH v2 18/19] powerpc: Cleanup idle for e500
Date: Mon, 19 Sep 2022 19:01:42 +0200 [thread overview]
Message-ID: <8039301334e948974c85ec5ef2db37751075185b.1663606876.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <828f6a64eeb51ce9abfa1d4e84c521a02fecebb8.1663606875.git.christophe.leroy@csgroup.eu>
e500 idle setup is a bit messy.
e500_idle() is used for PPC32 while book3e_idle() is used for PPC64.
As they are mutually exclusive, call them all e500_idle().
Use CONFIG_MPC_85xx instead of PPC32 + E500 in Makefile and rename
idle_e500.c to idle_85xx.c .
Rename idle_book3e.c to idle_64e.c and remove #ifdef PPC64 in
as it's only built on PPC64.
