Thanks for the quick response :) I have made some inline comments
Additionally I have fixed the __dtb_z_ unrelated issue, but still
troubles to get some output. Could you maybe send me a barebox binary
for an mx6 or mx7 board? I'm still unsure if it has the correct binary
format.
My current Kconfig values look like this. Maybe you can see something
missing.I have patched drivers/regulator/Kconfig (ARCH_IMX7) so that I
can enable REGULATOR_PFUZE, which is used on the tqma7d board. From
what I can see the NXP i.MX7 SabreSD board uses a PF3000 PMIC too so
iam unsure why it can work without this fix.

I don't think u-boot does something extra in c code, but i'll check
again. The board config in u-boot is stripped down so that it only
probes info through the device tree.
And the DCD table is exactly the same in the compiled output.

I'm sorry it somehow got mangled when sent :/

I missed some of the last comments but I have already enabled
CONFIG_DEBUG_LL and can't get any console output to appear. UART4 has
been selected in the menu for this.
