This memory is different from the HY57V561620 and MT48LC16M16 types I know and
Barebox is adapted to.
Maybe your system doesn't come up due to a wrong SDRAM configuration.
You should compare the SDRAM datasheets and check if the SDRAM controller
settings in Mini2440 'config.h' match the requirements of your SDRAM type.
