I'm currently running mainline u-boot, and hoping to test the series
that powers down secondary cores on the odroid-xu3.  That series applies
and builds with mainline u-boot (v2015.01-rc3), but for it to work
correctly, IIUC, I'll also need to build an SPL from mainline.

Can you share your changes to mainline u-boot that enable the building
of SPL?

I'd like to try that using your BL2 that will load an unsigned BL2.

Thanks,

Kevin
