the following patch was just integrated into master: commit 096f45792670acbd3c68cf01c07aad679f831d3d Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Mar 31 13:49:00 2016 -0500 lib/prog_loading: introduce prog_segment_loaded() In order to not muddle arch vs chipset implementations provide a generic prog_segment_loaded() which calls platform_segment_loaded() and arch_segment_loaded() in that order. This allows the arch variants to live in src/arch while the chipset/platform code can implement their own.
