Checkout the following branch. This is what I'm working on. build the
imxdt_defconfig. It builds a barebox which runs on all i.MX as a second
stage dt probed barebox. It's work in progress, so I guarantee for
nothing. The imxdt is basically a normal board support. We now have the
entry to barebox under board control, so this can be used to pick up the
oftree, look for memory nodes and pass the memory on to barebox. The
third argument is used to keep a pointer to the devicetree which is then
later used from the board to probe.
As the name suggests, this is currently i.MX specific, but it doesn't
have to be.
BTW for those who want to test this branch, barebox needs some nodes
currently not in all mainline dts files (ccm and gpt, linux,stdout-path
property in chosen node). Let me know when you are interested, I have
some example files.
