[PATCH] [RFC] cmd: pxe_utils: Limit fdtcontroladdr usage to non-fitImage

Commit d5ba6188dfb ("cmd: pxe_utils: Check fdtcontroladdr in label_boot") forces '$fdtcontroladdr' DT address as a third parameter of bootm command even if the PXE transfer pulls in a fitImage which contains configuration node with its own DT that is preferrable to be passed to Linux. Limit the $fdtcontroladdr fallback utilization to non-fitImages, since it is highly likely a fitImage would come with its own DT, while single-file images do need a separate DT.

I'd suggest adding an explicit comment in the code too, so it is easier to understand when this gets refactored later.

I sent a fixed version of this patch, can you add this RB to it too ?
Regarding comment in the code, there is already one massive comment explaining it just above, see the pxe_utils.c content in the sources.

" * Scenario 3: If there is an fdtcontroladdr specified, pass it along to * bootm, and adjust argc appropriately."
But are you not changing that? So update the comment?
