Can you tell me where you found this information?
[1], [2]

That would also mean all of your writes are kind of skewed, unless
you already applied some offsets to them.
This region is used by the modem, but must be set up
by the AP.
(IMEM on 6350 starts at 0x14680000 and is 0x2e000 long, as per
the bootloader memory map)
On SM7250 (sorry, I don't know about 7225, or 6350 for that matter),
the IMEM starts at 0x14680000 and has length 0x2c000.  However that
memory is used by multiple entities.  The portion set aside for IPA
starts at 0x146a9000 and has size 0x2000.

This is awesome, thank you!

Yes I think there are a couple of minor corrections to make
but I haven't had the time to go do the research yet, so
hadn't yet responded.

Nothing is "supported" upstream anyway until there's a
system with a DTS that uses it, and that won't happen
until after the end of the merge window.

Again, thank you very much, it's a safe thing to take
for now.
