[PATCH 25/26] tests/boot_linux_console: Add sdcard test for the Exynos4210

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <address@hidden>

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

Since this test is not reliable due to clock timing issues,
it is disabled with the 'skip' property.

v2:
- use archive.gzip_uncompress (Cleber)
- check getenv(AVOCADO_ALLOW_UNTRUSTED_CODE) (pm215)
