[Arm-netbook] EOMA68-A20 usb fel-boot and u-boot upload (no GPL-violating allwinner boot0 or boot1 involved)

[luke.leighton]

ok i have the usb fel Bus 003 Device 083: ID 1f3a:efe8 still on the
bus, so the A20 3.3 kernel source from allwinner isn't resetting
USB-OTG properly.  i forced it into "client only" mode which meant
that it didn't segfault at least.

anyway, i also got /dev/fb0 on HDMI up and running, as well as
connecting a USB 4-port hub, with keyboard and mouse.  if i had a
USB-Ethernet dongle i could connect to the internet.

so whew going from "it's all gone to shit with gpl violations in the
way" to "actually you can use this do at least do some testing, it's
not perfect but it's doable" within about 3 days which is great.
