Does that mean that in that case you need all regions to be 64k aligned? I mean secure and non-secure. Has anybody tested 64k pages under qemu?

Maxim.
I.e. I see comment:
- Note that devices should generally be placed at multiples of 0x10000,
- to accommodate guests using 64K pages.

but it's not clear why UART, RTC and GPIO is not aligned to 64k.
Er, 0x09000000, 0x09010000 and 0x09030000 are all 64K aligned addresses.
thanks -- PMM
thanks, will send an updated version.
