That's correct. I have experimented and it works fine. All we have to do is to
SEL header part.

Agreed. But this script is coming from hostboot (?) guys. We have to work with them

We can do this .. Its pretty much reverse procedure of eSEL logging from OPAL.

At least on x86 machine they allow us to download :-) So I assume its supported
here as well.. (only assumption, I never tried it myself).

Note that currently I'm looking into inband support for retrieving serviceable
eSEL event (whatever logged by OPAL, Hostboot and OCC?) .. Pretty much similar
to what we do in FSP based machine..
If we add that support, then we don't need to modify opal-elog-parse.. It will
just work.. So I think lets wait until we sort out inband mechanism..
