If you grep for firmware-imx in the u-boot source code you will find mentions of it in the READMEs documentation for many I.MX8 boards. So that firmware probably need to be reimplemented as free software somehow. Alternatively there are some new system on module (SOM) boards that are also compatible with the MNT Reform[1] that might at least boot with free software. I've also started documenting the MNT reform on a Liberplanet wiki page[2] but it's really a draft at this point.
