Thierry mentioned on the cover [0] that he is trying to get the
bootloader I'm targetting updated to use the reserved memory tables
already supported by mainline. If that gets done, this series becomes
unnecesary. So I'd like to put it on hold for a little while to give a
chance for that discussion to happen internally. If the response is
negative or there's no response after a while, I'll pick it back up.
To give a bit of context that answers several of the review comments
though, these dt node names and types are hardcoded in the bootloader
and thus cannot be changed. Like the sub-nodes are named
emc-table@...mcode and emc-table@...eq, which then triggers errors on
the schema example if reg is not defined. And if I have a reg in the
example, then I have to put it in the schema. Etc, etc.
Sincerely,
Aaron
