From b3ea575770c7eeb259c77b6861cd14d00eb309df Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Tue, 6 Jun 2017 20:50:42 +0300 Subject: [PATCH 2/3] ARM: imx: Add MXC_CPU_IMX6ULL and cpu_is_imx6ull Support for imx6ull is already present but it's based on of_machine_is_compatible("fsl,imx6ull") checks. Add it to the MXC_CPU_* enumeration as well. This also fixes /sys/devices/soc0/soc_id reading "Unknown".
