[Skiboot] [PATCH 00/51] ipmi-hiomap: Tests and fixes for event handling

[Andrew Jeffery]

Hello!

This series drastically improves the test coverage for HIOMAP over IPMI, and
fixes various bugs along the way. Once the series is said and done we have
90.9% line coverage and 100% function coverage of libflash/ipmi-hiomap.c

The bugs fixed along the way include issues with bits of infrastructure that
crop up when invoking `make coverage-report` as well as bugs in error state
handling in the IPMI HIOMAP implementation itself. The series was inspired by a
bug report by Vasant; patch 09/51 should fix that particular issue.

I've done each test case as a patch as they're pretty verbose, and reviewing
thousands of lines in one patch isn't my idea of fun, so I assume it's not
Stewart's either.

The series has been lightly tested on a Witherspoon system, with various
restarts of mboxd, ipmid, the BMC itself and the host thrown in. No issues were
encountered.

So, please review! Several beers to anyone who can Reviewed-by: the entire
series.

Andrew
