I installed an SPI flash device on the iMX6-smart-devices board and have a working interface to that.
I am currently booting/rebooting my board over USB using the imx_usb tool. Now I want to transition
a usb-based boot to SPI-boot. First, I have to reconfigure the BT_CFGX bits, and then it appears to me
that I can use the exact same image I boot over USB as the boot image for SPI-flash, true?
