Well, I'm not familliar with the MIPS system but the load address and
entry point look suspicious. According U-Boot README and my own
experience they should be either 0 (newer linux kernels) or 0xc (older
one). Did you use mkimage on your own?

Any further notes/debugging statements also are appreciated. Please try
to enable boot progress report (CONFIG_SHOW_BOOT_PROGRESS) to make sure
that not u-boot is the culprit.
Also good point to look for (rtfm): use linux image map file
(System.map) for log_buf and try to read from given address -> some
information what might have gone wrong *before* the kernel was able to
establish a terminal connection. This requires some debugging facility.
Please tell us something about the environment (embedded, console etc).
