U-Boot continuous integration

Real world example on U-Boot developing for CV300 board:

set -e

# In case of buggy USB UART adapter
sudo usbreset /dev/bus/usb/005/007

# In U-Boot directory:
make ARCH=arm CROSS_COMPILE=arm-hisiv500-linux- -j$(nproc)
cp u-boot.bin full-boot.bin
cp reg_info_hi3516cv300.bin ./hi3516cv300.reg
make CPU=hi3516cv300 ARCH=arm CROSS_COMPILE=arm-hisiv500-linux- mini-boot.bin

#./mkboot.sh reg_info_hi3516cv300.bin u-boot-ok.bin
cp mini-boot.bin ~/git/burn

cd ~/git/burn
# Custom script to power reset camera via network switch
./restart_eth4.sh
./burn --chip hi3516cv300 --file=mini-boot.bin
