I see that "Boundary Devices SABRE Lite/BD-SL-i.MX6" is listed as supported on the armv7 page, but I'm unable to get it working because of the EFI interface requirement for the firmware.
1. `run findfdt` outputs `## Error: "findfdt" not defined` 2. `bootefi` is an unknown command I believe this is because the device was shipped with U-Boot 2015.07-15072-g45cfc85, and the latest branch the vendor's released is based on v2016.03 ( https://github.com/boundarydevices/u-boot-imx6/tree/boundary-v2016.03). According to 'INSTALL.armv7', we need U-Boot 2016.07 or newer. Would love to know if there are other ways to boot in.
