From 096f45792670acbd3c68cf01c07aad679f831d3d Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 31 Mar 2016 13:49:00 -0500 Subject: 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.
