The function get_sdr_cs_offset reads the CS_CFG register in the SDRC to determine where CS1 is mapped to. make_cs1_contiguous() will set CS1 to follow after CS0. The CS_CFG register has values in bits 9:8 and 3:0 but we had erroneously been testing 5:4 and 3:0 resulting in incorrect offsets on platforms with less than 128MB as 3:0 describe 128MB hunks and 9:8 describe 32MB offsets after the 128MB hunk.
