This is not really the same thing.

This prevents from having U-Boot proper in SPI and TPL+SPL on eMMC/SD 
card. Is this a real usecase? I don't know, we do support it on Puma 
(though I know you haven't changed it in this commit). I guess we could 
still have the devices with SPI flashes have their own 
u-boot,spl-boot-order if they want.

So, in short, I would at the very least document this new limitation in 
the commit log but have nothing against the change (my board not being 
impacted by it :) ).

Cheers,
Quentin
