s/_/-, here and below. The names of child devices are user-exposed via
QOM canonical paths.

You already have obj for the OBJECT casted version of s.
Why do you us memory_region_init_io though instead of
memory_region_init? This looks like a container MR which is what
unqualified memory_region_init provides.

Same here. Although this container seems to have only one subregion at
offset 0 (the property device). Long term, will this MR have more
stuff in it or will always be just the property?

Not sure about this. Alistair (from Xilinx) has a similar problem
where the SoC needed to do a complex split of the single DDR into
multiple system address regions. I cc'd you on a patch. Following
Alistair's patch in the Xiinx ep108/zynqmp work, the system_memory
region is now fully owned by the SoC level and disused by the
machine/board level. I would suggest something similar here. The board
is responsible for creating (and mainly sizing) the RAM, and links (or
const-link's) the RAM to the SoC where it can be subregioned as-is
without this search. As you already have SoC level memory regions for
your multiple address spaces, you may actually end up with
system_memory being completely unused (and that is OK).
> + assert(ram != NULL && memory_region_size(ram) >= 128 * 1024 * 1024);
What is is the significance of the 128MB lower clamp? This should
probably be a weaker error than assert. Depending on the reason for
the error, it could be located in a number of different places. If the
SoC cannot function without 128MB for some reason this is the right
place.
If it is for forcing the user to not pass something to -m because that
is simply not what is on the board, then it should be done on the
board level. I'm thinking it would be reasonable to defeature -m for
these fixed boards as it does make less and less sense.

This comment location seems odd. Should it just go with the definition
of mbox_mr? It could possibly be a top level comment too.

These are all self-documented by the already-well-named s-> fields, so
you can drop these comments indicating what you are realizing.

I think this is in the same basket as the header from P1. We should
cherry pick out the defs that we care about (or are likely to care
about in near term follow up). I'm guessing this is sourced from the
same Linux fork as before?

Can you just keep it as one big 64-long list? I don't think we need

This 64 shouldn't be needed anymore with the arm_irqs now in their own
enumeration space. It should just count from 0 again (and I think the
only usages you have of these subtract off ARM_IRQ0_BASE).

The defs after here are confusing. Are they for a different SoC? I
thought the SoC was limited to 8 ARM_ irqs?
