This is really handy - Thanks Werner!

I've gone back over the CPU pintypes, and corrected a few in the 
attached patch.

I realised that I made an implicit assumption about a large number of 
pins that are type t8 or t12.  These are nearly identical bi-directional 
pins, that seem to also be tri-state in output mode.  I've labeled all 
those as BiDi - but would these be better as 3-state?

/CE & /WP don't seem to be in the table of i/o types I've been using 
(table 1-2), but 'input' seemed right to me...
