[U-Boot-Users] Boot password

I am using a board similar to IXDP425 and would like a password for boot. I have defined CONFIG_AUTOBOOT_KEYED And also defined: CONFIG_AUTOBOOT_PROMPT and CONFIG_AUTOBOOT_DELAY_STR

We got the CONFIG_AUTOBOOT_PROMPT but it sayed forever or until we typed the password.

When compiling we got undefined reference to get_ticks and get_tbclk We copied these functions from cpu/arm925t/interrupts.c to cpu/ixp/interrupts.c

What might have gone wrong?
