Thanks! I've been playing with your layer. For the most part it's going
well. I've noticed a small glitch, however, and I'm not 100% sure how to
fix it (otherwise I would have just sent you a github pull request).

If I have your layer added to the BBLAYERS mix but I'm _not_ building
for "odroidc1" (or "wetekplay", I assume) then I get an error because
the build system can't find the amlsetfb.sh file. You have two
"amlsetfb.sh" files, one for the odroidc1 and one for the wetekplay
which you've added to recipes-core/initscripts/odroidc1 and
recipes-core/initscripts/wetekplay. If the MACHINE is odroidc1 then the
recipes-core/initscripts/odroidc1/amsetfb.sh file is found, otherwise it
is not.

I can work around this issue by adding a MACHINE-specific override to
your initscripts_1.%.bbappend:

-SRC_URI_append = " file://amlsetfb.sh \
+SRC_URI_append_odroidc1 = " file://amlsetfb.sh \

but I'm guessing another override would be required for the wetekplay as
well.

Why would someone include your layer and not build for odroidc1 or
wetekplay? Sometimes that's what people do ;-) (look at Angstrom, for
example). Besides, a BSP layer should be able to play nicely with other
layers even when its machines aren't being used :-)
