I made a new arm machine with some peripherals. The machine is mk64fn1m0, a
cortex-m4 microcontroller from NXP Kinetis family. The machine can run a
simple arm binary file using UART0 in polling mode.
I have prepared a series of patchs to include this machine:
PATCH v3 n/11: It adds the machine and peripherals devices;
PATCH v4 n/2: It changes the Make files to compile this machine.
