Sure, understood. So if we always build uImage as "make uImage
LOADADDR=0xxxxx" then it will always work. No matter if you are in a
single machine defconfig or on a multiple machine defconfig.
What I think it is strange is the need to pass the UBOOT_ENTRYPOINT to
poky and then we need to force "LOADADDR=${UBOOT_ENTRYPOINT}" again in
our layer. Why can't poke just always pass
LOADADDR=${UBOOT_ENTRYPOINT} itself? If UBOOT_ENTRYPOINT is not passed
then it does the usual "make uImage" method.
because if you look at kernel.bbclass, it's only using
UBOOT_LOADADDRESS ?= "${UBOOT_ENTRYPOINT}"
in
do_uboot_mkimage() {}
which is executed once the kernel is compiled :
addtask uboot_mkimage before do_install after do_compile
And, if you follow what happens when our kernel is built, you will see
that uboot_mkimage is never called
