The reason I have to limit it with ARCH_QEMU in this patch is due to the
fact that currently
only board "qemu-arm" has implemented the required platform custom function
"board_bloblist_from_boot_arg()".
We can remove this limit and make it depend on the BLOBLIST only when all
arm boards
implement the required function.
But at least now, with this patch, we need it under ARCH_QEMU, otherwise we
will have
linking errors when BLOBLIST is enabled on a board which is not "qemu-arm".
For the future, I agree, this only depends on ARM, BLOBLIST and OF_BOARD.

Thanks and regards,
