You put a wrong value (0x4700000) into the IMMR in the BDI configuration file. U-Boot is configured to start with FADS default IMMR (0x0F000000), then it changes it to 0xF0000000 which is acceptable for Linux (unlike 0x4700000). When U-Boot first access the internal RAM using CFG_DEFAULT_IMMR (0x0F000000), bus error and subsequent reset happen because BDI already changed the IMMR.
