Re: [PATCH v3] arch: Kconfig: Let all architectures set endian explicitly

Hello all:

It seems no any additional rejections for it. I guess, I need split the
'big' patch into pieces, and each send to its' related mailing list, so
let it not like a spam. And the schedule may like:

 - Firstly, send patch for "init/Kconfig" to add CPU_*_ENDIAN. If pass
   checking (hope it can be passed checking), then

 - Send each related patch to each related architectures which already
   knew their ENDIAN attributes in config time (24 patches, I guess),
   then

 - Make patch for Kbuild to support __BUILDING_TIME_BIG_ENDIAN__, and
   pass checking (hope I can finish), then

 - Finish left architectures which need __BUILDING_TIME_BIG_ENDIAN__
   (4 patches, I guess).

Welcome any ideas, suggestions, or completions. And if no additional
reply, I shall not send any additional information any more to avoid
spam to other members.


Thanks.

Hello Maintainers:

Is this patch OK? If it pass basic checking, please let me know, and I
shall try to make another related patch for KBuild (I can do nothing
related with Kbuild, before get confirmation for this patch).

Thanks.

OK, thanks, I assumes when support both endian, the default choice is
CPU_BIG_ENDIAN, although no default value for choice (originally, I did
worry about it).

So I think you can just drop the MIPS segment from your patch.
If what I assumes is correct, what you said sounds reasonable to me.
So for me, it is harmless to add CPU_*_ENDIAN explicitly, and can let
other members don't need think of.

By the way, for sh, it is almost the same case, except it contents the
default value, for me, it is clear enough, so I skip sh architecture in
this patch.


Thanks
