Thanks for your valuable suggestion. I have checked the targets supported
by openwrt for Northstar processors. It provides kernel and rootfs builds
for Northstar based boards. (tried MR32)
I am unable to find the u-boot build for the Northstar based SoCs. How do I
enable the u-boot build as well for any of these boards?

It would be great to see the support for Northstar boards in the buildroot
as well.
