fsl_micfil_use_verid() can help to parse the version info in VERID and
PARAM registers. Since the two registers are added only on i.MX93
platform, a member flag called use_verid is introduced to soc data
structure which indicates acquiring MICFIL version.

When booting on e6500 with an ELF v2 ABI kernel, the secondary threads do
not start correctly:
[0.051118] smp: Bringing up secondary CPUs ...
[5.072700] Processor 1 is stuck.
This occurs because the startup code is written to use function
descriptors when loading the entry point

Can framer be a NULL pointer? This sort of test often covers up
bugs. So either let it dereference the NULL pointer and opps, or
return -EINVAL.

Please don't use inline in .c files. Let the compiler decide.

priv is a void *, so you don't need the cast.

I cannot really judge the ppc specific part but other patches seem
reasonable. Patch 4 could print a more useful information about the
wastage but this is nothing really earth shattering. I am not sure about
the last patch which makes the on-memory property dynamic. This needs
much more
