PS4, Line 135: In endianness of the firmware. Not meant to be stable.
> Since endianness of log itself is fixed, I think it makes sense to fix these fields as well. […]

Can do this after latest changes. If we're even considering use by something other than coreboot, these should probably also have some magic number and a version, otherwise fixing endianness won't be very helpful.
