We were told in the leadership meeting where this binary was discussed that it did not have access to memory or other x86 resources. Some PCI devices are controlled by either the x86 or the PSE, but can't be accessed by both at the same time. Sheng was going to verify that this was the case, in which case, it's just like any other embedded controller in a laptop. We don't print warnings for those, so we probably shouldn't for this either.

Well, since the PSE is a ARM SoC and running it's own OS, ofc it's runtime persistent. The question here is how it is connected to the main SoC and what accesses are possible (memory access like ME?).

It's not just another blob. It's runtime persistent and Martin brought the security
aspect up on the ML. I'd actually be surprised if there is any security for the OS.
Maybe we should add a warning about that as well? in Kconfig? printed after the
build?

The line makes 0x2000 bytes (8KiB) of RAM accessible to the ASL code around
it. This reserved RAM region is used for communication between the ASL code
and the OS graphics driver. I don't see anything wrong with it nor a way to
do it differently. I've seen the size specified in a document from 2008.
Might be a bug in the windows graphics driver. Have you tried Linux; if it
complains about anything in dmesg? What boards do you have?
