We could just modify the reg size but to allow more memory. I tried

Probably, DDR init code in HSS only initialized 1GB of memory.
Yes, it is only looking at the low window which is 1GiB max.
If it used the upper window it would get the 16GiB.
I don't know how no-one noticed this issue before shipping a board
out with this. I have updated the firmware on my second board but
this only seems to currently fix a reboot issue with the eMMC.
We can't update the DT for Linux until there is a public release of
the updated firmware
with 2GB enabled.
Yeah, it is really annoying the boards turned up with a number of
issues including the half memory.
I assume there will be a new release of HSS and U-boot which at
worse can insert new memory nodes into the device tree.
