Get a current version of OpenOCD [1], and replace that part by
source [find interface/jtagkey.cfg]
There's already a config for that JTAG adapter.

Replace that by "jtag_khz NNN" where NNN is the top speed
you want to use ... up to 6 MHz with that adapter. Don't
start too fast, it may no work. "0" won't work, it means
adaptive clocking and your JTAG adapter can't do that.

In your case won't say "arm9", say
source [find target/samsung_s3c2410.cfg]
Re the rest, have a look at the User's Guide [2] for advice
about how to set up your config files. You'l want to set
up your NAND flash etc; maybe there's a board config that's
enough like yours that you can just modify it.
