clearfog: U-Boot changes
This also updates U-Boot to 2018.01. Among other things, it makes the
USB-3 front port available, and mass storage works, yay!
Here's how I made `kwboot` available, BTW, for UART booting. It was run
in a fresh checkout of the current U-Boot's master:
export PATH=/home/jkt/work/prog/_build/br-cfb/host/bin:$PATH
make CROSS_COMPILE=arm-linux-gnueabihf- clearfog_defconfig
make CROSS_COMPILE=arm-linux-gnueabihf- tools
make CROSS_COMPILE=arm-linux-gnueabihf- -j4
./tools/kwboot -b ./u-boot-spl.kwb -t -p /dev/ttyUSB0
