From 97a759c057a0506c5d2561215af1634a6fd27732 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sat, 21 Sep 2019 21:14:28 +0800 Subject: [PATCH] ARM: OMAP2+: Fix omap4 errata warning on other SoCs [ Upstream commit 45da5e09dd32fa98c32eaafe2513db6bd75e2f4f ] We have errata i688 workaround produce warnings on SoCs other than omap4 and omap5: omap4_sram_init:Unable to allocate sram needed to handle errata I688 omap4_sram_init:Unable to get sram pool needed to handle errata I688 This is happening because there is no ti,omap4-mpu node, or no SRAM to configure for the other SoCs, so let's remove the warning based on the SoC revision checks. As nobody has complained it seems that the other SoC variants do not need this workaround.
