From 04b249656ebf311080a8efbbc0022acb38beca13 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 21 Dec 2018 06:21:15 +0000 Subject: imx8: scu: use dedicated MU for SPL SPL runs in EL3 mode, except MU0_A, others are not powered on, and could not be used. However normal U-Boot use MU1_A, so we could not reuse the one in dts. And we could not replace the one in dts with MU0_A, because MU0_A is reserved in secure world.
