BL2 run next image failed

Hi, I'm testing lsdk2012 atf code on LS1028. BL2 has loaded BL31 and U-Boot image successfully, while there is no more print info when BL2 calls bl2_run_next_image. The print info as following:

NOTICE: 4GB DDR4, 32-bit, CL=11, ECC off

DDR initialization is a key step at BL2 stage that later boot stages
and the OS rely on. Making sure it creates a reliable DDR memory configuration is essential for the rest of the boot process. You can find advanced information
on DDR ATF driver in L SDK User Guide, Section 5.2.1.1. The document can be downloaded by following this link. DDR settings are specific to the board and
used memory chips, thus no universal settings can be provided. My suggestion in
regards to the described issue is to use the DDR tool from QCVS software suite
to setup and verify your configuration before you proceed with debugging of the
rest of the boot code.

I'm also moving your recent inquiry about caslat_x to a new thread to be
followed by another engineer with expertise in DDR memory hardware. If you have
more questions specifically about ATF or ATF debugging, please feel free to update this thread.

For questions that are more DDR memory related and specific LS1028A DDR controller
initialization, please post in the new thread.

Best Regards,
Platon.
