Understatement of the year right there :)

This (of course) isn't an OpenBMC specific problem, but rather an
opportunity for OpenBMC to clearly excel against other BMC
implementations.

I'd love to see even the parsed ESELs show up through the REST API,
rather than the current mess which is literally just "printf("ESEL=%02x
%02x %02x...)".

If we have a PEL hidden in there, there's existing userspace to parse it
too (opal-elog-parse), and there's no reason why the BMC couldn't just
output the text representation of it all in addition to the binary.
