Subject: arm: dts: imx8ulp: Ensure mu@27020000 and lpuart5 availability during all boot phases
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=091df90a89ecd2526c6ba401c1b55af6b77da95e;p=pandora-u-boot.git

arm: dts: imx8ulp: Ensure mu@27020000 and lpuart5 availability during all boot phases

mu@27020000 is required for communication with ELE firmware, and
lpuart5 is the standard output device. Both peripherals must be
available before U-Boot relocation. Use bootph-all instead of
bootph-pre-ram so these nodes are retained across all boot phases.
