These were copy/pasted from SynQuacer, I suppose?
Ideally, these should point to some memory that is not exposed to the
OS, so that the PEI phase cannot corrupt a capsule image that has been
left in DRAM by the OS.
This only becomes relevant once we implement support for PSCI warm
reboot, otherwise DRAM will be cleared anyway. However, pointing these
into a random slice of main memory feels a little risky.
Do you have non-secure SRAM on this SoC?
