Re: [U-Boot] [PATCH v8 2/3] Odroid-XU3: Add support for Odroid-XU3

Dear Jaehoon Chung,

Hi,

CPU: Exynos5800@1200MHz Board: Odroid XU3 based on EXYNOS5422

Exynos5800? is it right?

Exynos5800 is a variant of Exynos5422 for chromebook, so they are almost same. The support for this SOC is merged earlier than Exynos5422. At that time, they used 5800 as its name instead of 5422. It does not make any difference in behavior, at least until now.

Why undef? Discard the previous setting value in exynos5-common?

Yes. With this lines, the previous setting is being discarded. To added commands such as autoboot, we have to override CONFIG_EXTRA_ENV_SETTINGS. But without remove it previous defined, the compiler complains about it. Is there other way for this problem?
