Sadly, it doesn't make a difference. Still no output.

grep -E '(DEBUG_KERNEL|DEBUG_LL|EARLY_PRINTK)' .config
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_LL=y
# CONFIG_DEBUG_LL_UART_NONE is not set
CONFIG_AT91_DEBUG_LL_DBGU0=y
CONFIG_EARLY_PRINTK=y

I have a call to ioremap in my custom board setup, but removing it
didn't make a difference either. So I guess other at91 boards should
be affected as well. My board is not that different from rn9200ek.
