The clock setting on this board depends on the existence of an external RMII crystal, which is not mandatory for the CPU itself.

"MCUBoot is a secure bootloader for 32-bit MCUs. The goal of MCUBoot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables easy software upgrade."[1]
This PR aims to add support for MCUBoot using the FRDM-K64F board.
The goal is to produce an ELF file specifically linked to take into account the allowed space for MCUBoot. This ELF file is then converted to binary, in order to add headers, hashes and signatures required by the bootloader.
The process mentioned above for the binary file is done by the imgtool.py script which is added in the dis/tools directory. This script is maintained by MCUBoot and I will update the script according to the changes upstream.
A new target
mcubootneeds to be called to generate automatically such binary, which can be flashed by callingmake mcuboot flash. In order to make the program work, MCUBoot needs also to be flashed into the device. This can be done through mynewt or zephyr by following the instructions on the MCUBoot repository.This is the first step towards MCUBoot full integration with RIOT, which should come soon.
This PR is based on #6986 to include last changes which will be done for the FRDM-K64F platform.
