PM code is generally broken and unmaintained, so no wonder. I don't remember if anyone has fixed CPU context restoration code (it uses a "skewed" stack frame).

I've just looked into the Au1550 datasheet and indeed it doesn't have such register; its SDDRAM controller is not compatible with older SoCs.

Looks like you'll have to invent something... ;-)
