Subject: Enhance layoutrom.py to work around a binutils quirk.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?a=commitdiff_plain;h=67863beb71e67433b38a20ba408e490ae173f324;p=seabios.git

Enhance layoutrom.py to work around a binutils quirk.

Some binutils (report of 2.20.1) don't create dummy symbols for each
section - work around that.
