Hi,
When CONFIG_SKIP_LOWLEVEL_INIT is defined, cpu/arm920t/at91rm9200/lowlevel_init.S is commented out and lowlevel_init() is undefined.
But cpu/arm920t/start.S will still use lowlevel_init(). See the code
--snip-- #ifndef CONFIG_SKIP_LOWLEVEL_INIT bl cpu_init_crit #endif --snip--
but cpu_init_crit() is still defined and use lowlevel_init().

Hi, Here my patch (I do not find it in the mailing list archives for some reason...)
