Agreed, apollon and omap2420h4 read this value at bootloader, Yes it's
meanless in qemu.
it's seted at initial bootloader, but it's not in qemu. If sdrc has
array value, we can read it

Yes, as you see almost same as n800.

It's initial support we need to work more to support full peripherals.

same as above.
If you don't mind I want to add mentioned devices later
