From: Alice Guo <[email protected]> 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.
The driver model for watchdog timer is not enabled yet, so disable wdog3 temporarily.
