playing with building fit images, and i started with mpc8315e-rdb,
built virtual/kernel using all defaults, and got this in images/:
modules--4.9.8+git0+b65e9b6153_6b67f448d6-r0-mpc8315e-rdb-20170315095945.tgz
uImage--4.9.8+git0+b65e9b6153_6b67f448d6-r0-mpc8315e-rdb-20170315095945.bin
uImage--4.9.8+git0+b65e9b6153_6b67f448d6-r0-mpc8315erdb-20170315095945.dtb
which is perfectly fine, since the machine conf file for that target
includes the line:
KERNEL_IMAGETYPE = "uImage"
now i start another (fresh) build, and add to local.conf the lines:
KERNEL_CLASSES = "kernel-fitimage"
KERNEL_IMAGETYPES = "fitImage"
now my use of the above is my (alleged) way of saying, "i only want a
fitImage", but given this snippet from kernel.bbclass:
# Merge KERNEL_IMAGETYPE and KERNEL_ALT_IMAGETYPE into KERNEL_IMAGETYPES
type = d.getVar('KERNEL_IMAGETYPE') or ""
alttype = d.getVar('KERNEL_ALT_IMAGETYPE') or ""
types = d.getVar('KERNEL_IMAGETYPES') or ""
if type not in types.split():
types = (type + ' ' + types).strip()
i apparently get both the default as specified in the machine .conf
file, *as well as* the fitImage i ask for. and, sure enough, in my
images/ directory, i have uImages and fitImages (and zImages, but i
believe that's because fitImages require them, so no big deal).
i suspect i could prevent the generation of uImages by using:
KERNEL_IMAGETYPE_mpc8315e-rdb = "fitImage"
but from a clarity point of view, would it not make more sense that if
someone had a line:
KERNEL_IMAGETYPES = " ... list of types ..."
that should override whatever KERNEL_IMAGETYPE is in the machine conf
file and generate *just* those images? or am i missing something here?

KERNEL_IMAGETYPE is the legacy variable and it's added to
KERNEL_IMAGETYPES for backwards compatibility.
If you update your machine config and local.conf over-rides etc to all
consistently use KERNEL_IMAGETYPES then the behaviour should be closer
to what you expect.
