From 5cd1f6bd7a44e8c3c62a548257bc5ceff61d1691 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 4 Mar 2016 10:36:40 -0600 Subject: [PATCH] ARM: keystone2: Allow for board specific speed definitions Its not compulsory that speed definition should be same on EFUSE_BOOTROM register for all keystone 2 devices. So, allow for board specific speed definitions.
