This patch adds support to flash zImage to the boot partition on eMMC. Usage: fastboot flash zImage <path_to_zImage>
So this replaces the kernel in an existing bootimage. What's wrong with "fastboot flash boot", "fastboot flash:raw boot <kernel>" or "fastboot boot <kernel>"? It is a bit fragile to be updating your kernel without updating the ramdisk. arm64 has no zImage, so this command is somewhat arm32 specific.
Fastboot is already plagued with a variety of implementations and behaviors. Some unification here would be good and just adding whatever various commands have been added to vendor u-boot's is not going to help. Adding to the combinations of things to test also bothers me.
+1. Just how much room do we have, or not have, to be compatible with existing tools but also abstract some of this out so that different boards can "I want a layout like this ..." (one set of kernel, device tree, initrd) and another "I want a layout like this ..." (two sets, for redundancy).
