Since this is target.mk as far as I can tell this selection does not work when DEVICE_TYPE is set within the device definition, but only when it's set in the (sub)target Makefile. As I understand it (and tested with make menuconfig), DEFAULT_PACKAGES is a per-target variable, and thus the DEVICE_TYPE from within the device definition will never be applied, and DEFAULT_PACKAGES.router will be used anyway for these devices.

True, question is then, should this really be called "DEVICE"_TYPE?
It's not like other DEVICE_* variables (DEVICE_NAME, DEVICE_PACKAGES or DEVICE_DTS).
Because the "targets" of ath79/ipq40xx/etc... wouldn't work if they all had to share
a single, common DEVICE_NAME/_DTS/_PACKAGE.
As for the MBLs, if I got this all correctly, that DEVICE_TYPE could be simply moved
to the apm821xx/sata target.mk

And it would work as expected, right?
