commit 9f4cbad60c2936872b0e95b7e625eadc3bc371d4 Author: Duncan Laurie dlaurie@chromium.org Date: Fri May 10 13:50:09 2013 -0700
Fix int15 return value for mainboard oprom handlers
These boards were returning 0 to indicate success when the realmode handler expects it to return 1 to indicate that it handled the interrupt.
