- Adds support for the Starcat Jupiter Nano SAMA5D27C-LD1G board - https://github.com/starcat-io/jupiter-nano - this board is very similar to the Microchip/Atmel SAMA5D2-Xplained board (sama5d2-xult)

/* There is a blue status LED on board the Jupiter Nano. It is driven

* driven by pin PA6. The LED is connected to ground so bringing the LED high
|
|
* will illuminate the LED.

* This LED is not used by the board port unless CONFIG_ARCH_LEDS is
|
|
* defined. In that case, the usage by the board port is defined in
|
|
* include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related
|
|
* events as follows. Note that only the blue LED is used.

* LED_STARTED NuttX has been started OFF
|
|
* LED_HEAPALLOCATE Heap has been allocated OFF
|
|
* LED_IRQSENABLED Interrupts enabled OFF
|
|
* LED_STACKCREATED Idle stack created ON
|
|
* LED_INIRQ In an interrupt N/C
|
|
* LED_SIGNAL In a signal handler N/C
|
|
* LED_ASSERTION An assertion failed N/C
|
|
* LED_PANIC The system has crashed FLASH
|
|
*
|
|
* Thus if the Blue LED is statically on, NuttX has successfully booted
|
|
* and is, apparently, running normally. If LED is flashing at
|
|
* approximately 2Hz, then a fatal error has been detected and the system
|
|
