You are passing -j1 to the command

Hello Tom,
I notice Kbuild fails to build venice2 board
because commit 52ef43b0529 added an empty Makefile,
arch/arm/cpu/armv7/tegra124/Makefile.
What shall we do with this?
Do you need v10 or shall I fix it in a follow-up patch?
Best Regards

Hello Simon and Tom,
This is my analysis of Kbuild performance.
[1] -j option is working
What I must say first is -j option is working correctly with Kbuild.
You can double-check by following the steps below.
Apply Kbuild series v8 on
commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07.

Hello Tom,
Now, this kbuild series cleanly applies on the current u-boot/master.
(commit 07e2822d158940a0e8ba45b6ab0344ffa1011a07)
What's your plan about this series?
Are we ready to switch to Kbuild, or need more review?

We switched to Kbuild style makefiles at v2014.01-rc1 release.
With that modification, we can write makefiles simpler.
But it is NOT real Kbuild. We need more progress.
As the next step, this series imports (+ adjusts) build scripts
from Linux Kernel under scripts/ directory.
