The only constraints are that both <start> and <start+len> must be aligned 
with erase block boundaries.

If you have a chip with 8*8K erase blocks followed by 15*64K erase blocks, 
then an erase of length 72K at offset 56K is permitted - you'd erase the 
last of the small blocks and the first of the big blocks.
