Future of Odroid N2 and HC4 usb boot & petitboot

With additional steps, all is possible, this is just to attempt to avoid the need to those additional steps and enable USB boot just OOTB, as petitboot is what Hardkernel’s SBCs with SPI are delivered with.

Ok.

It would be nice then to have that steps to achieve diferents results.
