[U-Boot] [PATCH 2/3] ARM: uniphier: enable SPL_OF_CONTROL

[Masahiro Yamada]

Device Tree really improves code maintainability and is now
available for SPL too.

This is the state-of-the-art implementation in U-boot.

The board files (platform data) are no longer needed.

Personally, I was very convinced with the last answer (Nov 14, 2012; 7:34am)
in this thread:
http://linux-kernel.2935.n7.nabble.com/acked-by-meaning-td551744.html



If you want to refer to a more official one,
https://www.kernel.org/doc/Documentation/SubmittingPatches


------------->8------------
Acked-by: is often used by the maintainer of the affected code when that
maintainer neither contributed to nor forwarded the patch.

[snip]

Acked-by: does not necessarily indicate acknowledgement of the entire patch.
For example, if a patch affects multiple subsystems and has an Acked-by: from
one subsystem maintainer then this usually indicates acknowledgement of just
the part which affects that maintainer's code.
--------------8<---------------


I think this is the typical usage of Acked-by:
http://patchwork.ozlabs.org/patch/508716/



In the kernel development, patch committers give Signed-off-by,
but it is not the custom in U-boot.
So, I guess it makes sense that custodians issue Acked-by instead of
Signed-off-by.

Oh, they did formalize it here. I didn't know about that, thanks!

We should certainly talk about the usage of SoB lines in U-Boot eventually.

That I am not so sure about. But, feel free to add my R-B to this patch if
you feel it's appropriate ;-)
