[U-Boot] [PATCH 44/82] x86: board_f: Update init sequence for 64-bit startup

Simon Glass sjg at chromium.org
Mon Sep 26 05:33:47 CEST 2016


Adjust the code so that 64-bit startup works. Since we don't need to do CAR
changes in U-Boot proper anymore (they are done in SPL) we can simplify the
flow and return normally from board_init_f().
