Thanks, Chris.

However, the issue is actually the default gcc mode is an arm processor without umull. The kernel config should add:
makeoptions     CPUFLAGS="-march=armv4 -mtune=arm9"

Or perhaps that should be in files.ep93xx. It would then benefit the whole kernel.

I revise epclk.c and files.ep93xx, and Armadillo-9 worked.

Has it made any obvious performance differences? Never sure it an optimized cpuflags kernel helps dramatically or not.
