Arnaud, do you agree with this?
Happy to take your patch via Nicolas, but for the maintainer entry I
would like to have some confirmation.

Having "Allwinner Technology" here is indeed weird and probably not
really justified anymore, given the "support" we see from Allwinner.
I wonder if we should scrap this for all boards. Also it makes the line
longer than 80 characters.

I answered in the other email about the boot delay already.

So what is the reason for all those other options below?
Is there any particular reason they were all disabled?
I can buy CONFIG_NET, but the rest seems unnecessary. There doesn't
seem to be a driver for the PineTab panel in U-Boot, so this is solely
suppressing a few lines on the serial? Since this would be surely for
debug only, I think it's useful to have them, normal users wouldn't see
them anyway.

We should definitely keep EFI_LOADER.
