Crochet can't see installed port u-boot-rpi

[tldrm]

Crochet stops with error "Please install u-boot-rpi and re-run this script." while the port is installed.

I was able to proceed after the following:

cd /usr/local/share/u-boot/u-boot-rpi
ln -s u-boot.bin u-boot.img

Looks like the file name has changed in the port.

Same for OrangePi-One.

cd /usr/local/share/u-boot/u-boot-orangepi-one
ln -s u-boot-sunxi-with-spl.bin u-boot.img
