NOR: add optional "flash erase_address" sector padding
Add a NOR flash mechanism where erase_address ranges can be padded out to sector boundaries, triggering a diagnostic: > flash erase_address 0x0001f980 16 address range 0x0001f980 .. 0x0001f98f is not sector-aligned Command handler execution failed in procedure 'flash' called at file "command.c", line 647 called at file "command.c", line 361 > > flash erase_address pad 0x0001f980 16 Adding extra erase range, 0x0001f800 to 0x0001f97f Adding extra erase range, 0x0001f990 to 0x0001fbff erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s) > This addresses what would otherwise be something of a functional regression. An earlier version of the interface had a dangerous problem: it would silently erase data outside the range it was told to erase. Fixing that bug turned up some folk who relied on that unsafe behavior. (The classic problem with interface bugs!) Now they can get that behavior again. If they really need it, just specify "pad".
