selfboot: Move the usable-RAM check into a function
In preparation for making this check optional, move it into its own function. load_self_segments() is already long and we don't want to make it longer. BUG=chrome-os-partner:56314 BRANCH=none TEST=boot on gru and see that BL31 loads and runs correctly Change-Id: If48d2bf485a23f21c5599670e77a7b8b098f1a88 Signed-off-by: Martin Roth <martinroth@chromium.org> Original-Commit-Id: 2381e02efa2033857ac06acbc4f0c0dd08de1080 Original-Change-Id: I005e5e4d9b2136605bdd95e9060655df7a8238cb Original-Signed-off-by: Simon Glass <sjg@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/381092 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://review.coreboot.org/16585 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
