Not that I am aware of this. Perhaps somebody at AppliedMicro?

Yes, ddr_scan_option() can be used to supply a board specific fix. But a
generic fix in 4xx_ibm_ddr2_autocalib.c would be much better of course.
Do you experience any possible DDR2 related problems on your 460EX/GT based
boards?
Cheers,
