Re: [PATCH v3 1/5] arm64: dts: ti: k3-j721s2*: Add bootph-* properties

U-Boot? Let's try to pretend like this is a generic property and
just say "bootloader" :)

Thinking out loud, what happens when we want to re-use these DT
source files in Zephyr, or some other software, will we keep adding
these new metadata tags?.. bootph-* and other "domain info" might
better belong to some higher level device tree source (System
Device Tree I'd guess, time to add Lopper to kernel? :D)

For now, lgtm,
