Without this, the arch-dtbs target only gets evaluated when building U-Boot the first time, not when re-building (incrementally building) U-Boot. Thus incremental builds ignore changes to DTB files.
Really?
I tested "touch DT, then incremental build", and it correctly re-compiled device tree.
I attached the log of the following build sequence:
[1] make jetson-tk1_defconfig [2] make CROSS_COMPILE=arm-linux-gnueabihf- [3] touch arch/arm/dts/tegra124-jetson-tk1.dts [4] make CROSS_COMPILE=arm-linux-gnueabihf-
Hmm, OK. Understood.
The jetson DT was recompiled, but the other tegra DT files were not.
Yes, perhaps I should have mentioned that I found this issue when building sandbox. Sandbox's default DTB of sandbox.dtb does get recompiled as expected, but test.dtb (used by the test/py/ test system) does not, for incremental builds.
