@deffn {Flash Driver} efm32
All members of the EFM32 microcontroller family from Energy Micro include
internal flash and use ARM Cortex M3 cores. The driver automatically recognizes
a number of these chips using the chip identification register, and
autoconfigures itself.
@example
flash bank $_FLASHNAME efm32 0 0 0 0 $_TARGETNAME

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