Minimal set:
1. Something with Exynos4 (e.g. Odroid U3 with Exynos4412).
2. Something with Exynos 5422/5800 (e.g. Odroid XU3/XU4/HC1/MC1 or
Chromebook Peach Pi).
3. Exynos5433 - TM2 or TM2E. Boards are not widely available, so we need
to rely on provided testing by Samsung.

What would be good is to also test Exynos3 boards, but this is also not
widely available.


Best regards,
Krzysztof
