[commit] r872 - in trunk/openbios-devel: arch/ppc/mol arch/ppc/pearpc arch/sparc32 arch/x86/xbox include/libopenbios libopenbios packages
Author: blueswirl Date: Wed Sep 29 22:30:51 2010 New Revision: 872 URL: http://tracker.coreboot.org/trac/openbios/changeset/872
Log: Avoid a lot of malloc/free traffic
Each console write caused temporary buffer allocation.
Avoid allocations by changing console_draw_str() to use Forth string parameters, which are usually readily available.
