Subject: ARM: imx: Add MXC_CPU_IMX6ULL and cpu_is_imx6ull
From: Leonard Crestez <leonard.crestez@xxxxxxx>
[ Upstream commit b3ea575770c7eeb259c77b6861cd14d00eb309df ]
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".
