For i.MX233 addition the base registers need to be change so the SoC definition needs to be known before the header include. The following boards has been changed: * apx4devkit * m28evk * mx28evk * sc_sps_1 Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Acked-by: Stefano Babic <sbabic@denx.de>
