I tried building, but my MIPS complier from debian (gcc version 6.3.0
20170516 (Debian 6.3.0-18)) wouldn't build it, and I got the same errors
from the version of the compiler you link above.

Is anyone working on more recent MIPS compilers?  For all the other
arches we're building with gcc-7 or gcc-8.

Anyways, I tried with you u-boot image, and that can DHCP so I'm on to
the next step.

I was then able to build mainline (pistachio_defconfig) and boot
mainline using the debian ramdisk and rootfs (mipsel) we build for
kernelCI!

In the process I found a couple things to fix in how we build/install
kernels for MIPS, so I've submitted some fixes for kernelCI infra.  Once
those are merged, we'll start getting regular builds and boots on my
Ci40 with kernelCI.

If you have other boards that might be interesting, I'd be happy to add
them as well.

Thanks for all the help getting this bootstrapped,

Kevin
