Agreed.

How so?

I think there was/is an issue with the fact that top5200 uses GPIO for 
the uppermost (A16+) address lines AND that FLASH is connected 8 Bit wide.
Maybe CFI code does support such by now, at that time it did not.

Since its quite unlikely I will make any changes to those boards in the 
future, they can be removed.
