While changing some other things in the probe I made this change, but I 
think this is not necessary, I'll change it to iterate from 0 to 
ARRAY_SIZE()

Not sure what you meant here. could you elaborate a bit?

I'll add it in the next version.

I thought that the base address would change with boards, but seems it 
doesn't change. I'll add this in the array.
