i just noticed that the machine config file for mpc8315e-rdb still
lists "uImage" as the default image type:
KERNEL_IMAGETYPE = "uImage"
IMAGE_BOOT_FILES ?= "u-boot.bin uImage uImage-mpc8315erdb.dtb;dtb"
is there anything about that target that still *requires* uImage
creation, as opposed to zImage?
given that uImage is considered u-boot's "legacy" format, is there
any drawback to making zImage the default image type, and letting
folks drop back to uImage if they choose?
put another way, is there anything that currently *ever* requires
the creation/use of a uImage format?

There are some boot methods/use-cases that only work with uImage. Not sure if
that's the case with mpc8315e-rdb though...
