If you have a z2 specific config, that would probably not enable CONFIG_OF,
which is always turned on for multiplatform, but again that only adds around
250KB in my builds (using gcc-11). This is more than I'd like it to be, but
still much less than 1MB.

Maybe it is a bit less; I only compared the size of "Image". Either case,
it is enough to cause the problem. I am not sure if it is worth the time
trying to track this down further.

Sure, I'm not worried about the boot regression any more, as that is definitely
explained by the size growth. The only question is whether the patches make
the kernel grow more than it should. The 40+250KB I measured seem
within my expectations, so unless you have specific data showing much
more, I think we're good.

Thanks for all the help!
