[U-Boot] travis-ci: Trigger build with multiple commits in one push

[Jagan Teki]

Hi Tom or Any,

Any idea how to trigger travis-ci with multiple commit (build all of
them) at same push, say for example when I push 10 commits in one push
and if the middle commit is an error commit but travis-ci doesn't show
the build issue. Do I need to do any specific setting on travis-ci
linked repo for this, or any - any help?

Jagan.
