Commit Message

André Draszik March 6, 2025, 10:14 a.m. UTC 
Now that we have the NVMEM, we can also hook-in the nvmem-reboot-mode,
so as to have Linux communicate the requested boot mode to the boot
loader via it.

The two remarks regarding missing reboot modes from commit ae32b65c9359
("arm64: dts: exynos: gs101: add reboot-mode support (SYSIP_DAT0)")
apply to this commit as well.
