How will this work for the updated detailed layout bindings that got
merged here:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=91ddd97e1bb26937a5c15fb51ec8f6b65dbe94b8

This splits up your one memory region into several memory regions. Here
is one patch that uses that new memory region:

  https://lore.kernel.org/all/20260701-topic-am62a-ioddr-dt-v6-19-v7-9-e9db8b16821a@xxxxxxxxxxxx/

This basically breaks up the one memory region into several regions.
Wouldn't this break the fdt_fixup_reserved_memory() that you are trying
to merge into u-boot and make this patch unnecessary?

Best
Markus
