PMICs and gpio-uclass patch isolated behind configs for these 2
drivers. No unintentional size increase on any board. (proposed

The problem is that the arm64 magic is checked before the image is
decompressed. However this is only part of it. The kernel_noload image
type doesn't work with compression, since the kernel is not loaded. So
this series deals with that by using an lmb-allocated buffer for the
uncompressed kernel.
Another issue is that the arm64 handling is done too early, before the
image is loaded. This series moves it to after loading, so that
compression can be handled.
A patch is included to show the kernel load-address, so it is easy to
see what is going on.
One annoying feature of arm64 is that the image is often copied to
another address. It might be possible for U-Boot to figure that out
earlier and decompress it to the right place, but perhaps not.
With all of this it should be possible to boot a compressed kernel on
any of the 990 arm64 boards supported by Linux, although I have only
tested two.
