This one is better... the build problems are now fixed.

But this one has the same problems as v4.1-rc1 and beyond: it still 
doesn't boot here on any OMAP34xx/OMAP35xx platform, nor the CM-T3517, 
OMAP4460 VAR-SOM-OM, or OMAP5430ES2 SBC-T54:

Thanks for posting your test logs above.  They don't include bootloader 
info, but my guess is that v4.1-rc* has some hidden bootloader 
dependencies where things aren't being initialized properly from the 
kernel.

So those should be tracked down and fixed before we stack more patches on 
top.
