Hi Masahiro,
Sure, but that is a separate issue, isn't it? We already support various boot targets in arm64 but not one that includes the DTs, so far as I can see. The old arm 'uImage' target is pretty out-of-date now.
Does that mean it can be removed? ;)
I've NAK'd FIT support on 32-bit Arm in the past, and I remain of the opinion that boot loader specific packaging of the kernel should not be in the kernel but should be external to it - even more so given the multi-platform nature of 32-bit Arm kernels.
I'll point it out here rather than Simon. As part of https://github.com/open-source-firmware FIT is a standard and not "boot loader specific". And one of the points of a FIT image is that you can easily support multi-platform kernels in a single file (without optimizing things further, at a cost in tens of milliseconds on a Pi 3 anyhow) and with user-controlled security.
