Largely due to DT there is a forced dependency between the two that we can’t avoid.

[CEM] I’m not sure this is true.  I think that older u-boot doesn’t understand zImage like new u-boot does. That is the limiting issue here.  Not that you can’t boot a 3.2 zImage or uImage with new u-boot.

But it is rather specific to u-boot, not the kernel...

But what happens to the 335x 3.2 kernel recipe? I am ok with the machine’s setting the default KERNEL_IMAGE but to unbreak similar recipes the KERNEL_IMAGE would need to be overridden.

All machines set their kernel image types. The default is uImage. Only those with newer u-boot and 3.12 kernel by default change to zImage. The old ones are still uImage.

Since the uImage -> zImage change is being pushed by U-boot I am assuming this has more to do with the newer U-boot versions. Since a lot of these kernels will not work on a newer u-boot I wouldn't make this change on any <3.8 kernel recipes.

I don't understand the reason for this switch so I could be wrong.
