From 8ebf506ab2729012a3fe7dd8765a7d24202d409b Mon Sep 17 00:00:00 2001 From: Claudiu Manoil Date: Thu, 7 Jul 2016 15:49:02 +0300 Subject: [PATCH] powerpc/85xx: Don't report SRAM to L2 cache fallback as error If the SRAM region parameters are missing the SRAM driver probing exits and the L2 region is configured as L2 cache entirely. This is the expected default behaviour, so it makes no sense to report it as an error.
