Marek,

I looked at the Travis logs, and it looks like the da850evm_nand and
da850evm_direct_nor were failing, so I tried to clone
git clone --depth=50 --branch=master
https://github.com/marex/u-boot-usb.git marex/u-boot-usb based on line
846 of the Travis log.

When I built da850evm_nand and da850evm_direct_nor, I could not
replicate either the build error.

The EHCI patch referenced above should not impact the da850 board
because that driver isn't loaded and the IP isn't present on the
da850evm.  They are a different OMAP family.

If you have some suggestions I how I can replicate this build error or
what I might be doing wrong, please let me know.
