This approch hardcoded the DBGU address based on the configuration.
Can you somehow come up with something that is run-time configured?
So we can continue towards the goal to have multi-image support
for at91.
The current approch will limit us to a single type of SOC -
and we may try to combine more than one SOC in the same multi-iamge
sometime in the future.
Maybe each board have to call an debug_ll_init(address) function or similar.
If not called we can use the default which is the common address
for most at91 SOCs.
Or maybe something smarter.
