[SeaBIOS] [PATCH 00/10] build: Allow 32bit sections to be at fixed locations

[Kevin O'Connor]

This series updates the build (and layoutrom.py in particular) to be
more flexible in section layouts.  Prior to this series, only code
compiled in the 16bit mode pass could be placed at a fixed address in
the f-segment.  After this change, the build can more easily place
sections from any compile pass.

Most of the series consists of minor cleanups to layoutrom.py to make
the above happen.  Patch 4 is an unrelated minor feature enhancement.

Otherwise, patches 7 and 10 are where the real changes occur.
