From 6c454fedf5195e4160bd7aa398f7a4bb17d7157c Mon Sep 17 00:00:00 2001 From: Bryan Wu Date: Fri, 15 Aug 2014 16:51:38 -0700 Subject: image: fix bootm failure for FIT image Commit b3dd64f5d537 "bootm: use genimg_get_kernel_addr()" introduced a bug for booting FIT image. It's because calling fit_parse_config() twice will give us wrong value in img_addr. Add a new function genimg_get_kernel_addr_fit() whichl will always return fit_uname_config and fit_uname_kernel for CONFIG_FIT. genimg_get_kernel_addr() will ignore those to parameters.
