+Subject: [PATCH 1/4] clearfog: generate random MAC address
+
+The Clearfog does not come with predetermined MACs.
+Falling back to random ones ensures ethernet can still operate anyway.

 Use GPIO19 which is wired to the uSOM phy reset signal in order to reset
 the uSOM's 88E81512 gigabit Ethernet phy.

+Subject: [PATCH 3/4] clearfog: enable distro boot code
+
+load addresses start at 0x02000000, leaving enough space for fdt,
+boot scripts and ramdisk at the end.
+Only boot from mmc, the other options are not in working order.
+Removed *_high variables in good faith. They can be re-added with sane
+values when, and if required.
