Single stepping with JTAG showed that some instructions were incorrect, and these instructions started from 32-byte boundary, suspected to be L2 cache issue. After disabling L2 cache, kexec was able to boot into the zImage OK.

And Marvell kindly provided the following two patches to solve this issue completely.
