- pic32mx
- ocl

@comment - defines mass_erase ... pointless given flash_erase_address
@end deffn
-@deffn {Flash Driver} ecosflash
-@emph{No idea what this is...}
-The @var{ecosflash} driver defines one mandatory parameter,
-the name of a modules of target code which is downloaded
-and executed.

Most members of the LPC1700 and LPC2000 microcontroller families from NXP
include internal flash and use Cortex-M3 (LPC1700) or ARM7TDMI (LPC2000) cores.
