From 6b9b5f3220b48bab7340fa7cae6ee021280fa9f1 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Mon, 22 Dec 2014 13:11:36 +0100 Subject: [PATCH 05/15] fw_cfg: move boards to fw_cfg_init_io() / fw_cfg_init_mem() This allows us to drop the fw_cfg_init() shim and to enforce the possible mappings at compile time.
