Getting dtbs_check Working

Just a Quick Note for Myself

I have off and on been working on getting a device tree files submitted for a Solid Run board that I own. I would like to have an easier time running OpenWrt on the board. Uptreaming for the win.

I had a well short attempt to add the device tree file as it came from Solid Run. So after working out the small naming problems I decided I want to try to use the dtbs_check functionality in the kernel makefile. In case I don’t get this merged upstream I want to document how to get this check running:

1. Get the kernel source tree
2. make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 KBUILD_OUTPUT=out/ defconfig
3. make CHECK_DTBS=y marvell/cn9130-cf-pro.dtb
