Subject: Permit multiple BEV and BEV/BCV combinations in a single option rom.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=seabios.git;a=commitdiff_plain;h=1e15725c92858a0cb1dd5c76bd44af1fec09fee3

Permit multiple BEV and BEV/BCV combinations in a single option rom.

The BBS spec is unclear on multiple BEV entry points for a rom.
However, the LSI scsi rom has been seen to register a BEV followed by
multiple BCV entry points.  Add support for it, as there's no harm in
it.
