Re: various submissions


Indeed there is a number of drivers that handle this but there are
devices for which it's not implemented.If controlled by a CDL it should 
not effect the rest of the FLASH.
And having the block sizes field approach as the generic intel 28f driver does
is pretty low impact.
And code would be cleaner in the drivers which now implement this.
