[DistroKit] [PATCH 5/5] v7a: add Wifx L1 SD-Card image

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The Wifx L1 is a SAMA5D4-based LoRaWAN gateway. This commit adds first
support for booting DistroKit on it from SD-Card.

Default boot medium is NAND, but a bootable SD-Card always has precedence
over NAND.

+SAMA5D4 boards
+==============
+
+DistroKit currently supports one SAMA5D4 board:
+
+ * Wifx L1 LoRaWAN Gateway
+
+
+Boot Media
+----------
+
+The L1 will boot from a bootable SD-Card if one is inserted and otherwise
+fall back to booting from NAND flash. DistroKit generates only a SD-Card
+image for now:
+
+ * ``platform-v7a/images/wifx-l1-sd.hdimg``.
