Expected result
===============
The 'red' and the 'green' LEDs of the board should light up alternating with a
500ms interval. If your board has only one LED (probably defined as LED_RED),
you will see only this LED blink at 1Hz. If your board has no on-board LED, you
will see nothing.
This test will blink all available on-board LEDs, one after each other in an
endless loop. Each LED will light up once long, and twice short, where the long
interval is roughly 4 times as long as the short interval. The length of the
interval is not specified and differs for each platform.
Background
==========
All boards in RIOT define at least two macros for accessing two selected
on-board LEDs directly. These are called LED_RED and LED_GREEN, independent if
the actual color of those LED is red or green.
Running this test shows if all the direct access macros for all on-board LEDs
are working correctly (xx_ON, xx_OFF, xx_TOGGLE). This test is intentionally not
using any timers, so it can also be used early on in the porting process, where
timers might not yet be available.
