The sequence erroneously launched the DDR controller initialization before the pad muxing was done, causing DRAM size computation to hang. Configuring the pads first then launching DDR controller initialization prevents the DRAM hanging. Signed-off-by: Albert ARIBAUD (3ADEV) <albert.aribaud@3adev.fr>
