This test boots a Linux kernel on a smdkc210 board and verify
the serial output is working.

The cpio image used comes from the linux-build-test project:
https://github.com/groeck/linux-build-test

If ARM is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:arm" tags.

This test can be run using:
