From 5b54860943dc4681be5de2fc287408c7ce274dfc Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Mon, 15 Nov 2021 10:05:32 +0100 Subject: powerpc/book3e: Fix TLBCAM preset at boot Commit 52bda69ae8b5 ("powerpc/fsl_booke: Tell map_mem_in_cams() if init is done") was supposed to just add an additional parameter to map_mem_in_cams() and always set it to 'true' at that time. But a few call sites were messed up. Fix them.
