Detailed Description

Boot error log master structure.

PBC error log structure. Includes the error ring, the pointers to the "head" & "tail", statistics and other info.

Many people like to refer to the head and tail of a ring buffer. That confuses me, (I can never figure out which is the head and which is the tail) so I use first (the oldest entry) and next (where the next entry would go).
