cm1_qp1 -> cm5200: single U-Boot image for modules from the cm5200 family.
Add the ability for modules from the Schindler cm5200 family to use a single U-Boot image: - rename cm1_qp1 to cm5200 - add run-time module detection - parametrize SDRAM configuration according to the module we are running on Few minor, board-specific fixes included in this patch: - better MAC address handling - updated default environment ('update' command uses +{filesize} now) - improved error messages in the auto-update code - allow booting U-Boot from RAM (CFG_RAMBOOT) Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Piotr Kruszynski <ppk@semihalf.com> Signed-off-by: Bartlomiej Sieka <tur@semihalf.com>
