I wanted to add something to this file, so I set up my own travis-ci.org 
account and made it run against my own github U-Boot repo "fork" to test 
my change. However, most of the builds failed before I even modified 
.travis.yml. For example:

> $ if [[ "${TOOLCHAIN}" == *arm* ]]; then sh eldk-eglibc-i686-arm-toolchain-gmae-5.4.sh -y ; fi
> Enter target directory for SDK (default: /opt/eldk-5.4/armv5te): /opt/eldk-5.4/armv5te

Do I need to perform some manual configuration of my 
repo/branch/profile/... before this .travis.yml will work correctly 
(container vs VM I wonder?), or perhaps obtain some kind of 
authorization from the Travis CI admins? If so, if that could all be 
documented in a comment at the top of .travis.yml that would be 
extremely helpful. Bonus points if it can be handled simply be adding 
extra configuration options into .travis.yml so that it "just works" 
without manual steps.
