It's mentioned several times,
How do you talk with other when talk about the smdk?
"I'm using the smdk machine and it's based on smdk machine?"
As board is more proper word and it's easy to know when find the board
at source code.
So hope to use the board if it's not big deal.

BR,

If you don't mind, I want to let you know additional information.

I also agree with Mr.Park.

Generally in the robot field, the term "machine" means the total things
including the machinery part and even the brain "board", and the machine
is more bigger concept.
Probably, in the other field, this confusion will be occurred
when they see the linux kernel source first.
So, I think these terms might be necessary to distinguish.

Thanks and Regards,
Heungjun Kim

Yes, we say 'SMDK board blah blah' so it can be no big deal, but I don't
want to make a confusion between CONFIG_MACH_XXX and mach-xxx.c yet even
though there is a similar situation of arch/arm/mach-xxx/ directory and
CONFIG_ARCH_XXX. In addition, the machine_is_xxx() is used to distinguish
board in the kernel.

Anyway, I think, if to use board-xxx.c is required, we can change it all at
once and let me think again.

Thanks.

Best regards,
Kgene.

Well, I don't think so. I'd like to ask why you _do_ think the meaning of
machine is bigger than board. General robot field?...Nobody knows machine
does not mean board in the arch/arm/ kernel.

If we use the meaning what you said the contrary is rather to be supposed.
The confusion can be caused.
And how about machine_is_xxx() and CONFIG_MACH_XXX for board?

...

Anyway, the board-xxx.c file can be used for it later but as I said, if
required, we need to change it all at once in samsung stuff not just for
TRATS board.

Thanks.

Best regards,
Kgene.

Don't think, use the current way.

You seem not to have the common courtesy to discuss something here.

Thanks.

I also have same opinion on you. Discussion(?) with you is meaningless
and don't see any progress.

Some platforms which the kernel runs on are not a 'board' but a set of
boards: a motherboard and a separate CPU card.  So to call these a
'board' is wrong too.

Welcome to the problem: there is not one single term which satisfies
everyone.  The solution: a compromise.

The compromise that has been chosen for the ARM kernel is to call this
stuff 'machines' or 'platforms' - and the exynos stuff has decided to
call it 'machines'.  (Some people have decided to use 'board' in their
directories, which is fine _provided_ there is consistency within that
directory.)

That's actually the _most_ important thing: consistency.  So if a
maintainer has decided to use one way in their directory, that's the
way which rules for that directory.  So, please, get over it - and
don't start a brand new naming scheme in a directory just because you
don't agree with the maintainers opinion.

So, please name the board mach-trats.c as requested by Kukjin (who is
the maintainer for exynos.)

The exynos4 dt-enabled board file can support most of the features
added in this board file. The other option that could be considered
here would be to add DT support for this board file, and use AUX_DATA
to supply platform data for drivers that do not have dt support yet.
It would be better to use dt support for new board support that we
add.

Thanks,
Thomas.

Thanks to Thomas' work TRATS can be booted today using exynos4-dt.
However, we are still missing some bits needed to make it fully functional:

 - sdhci-s3c patchset[1] is needed for eMMC support

   http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/9216

 - irq-eint[2] and max8997-pmic[3] for regulators

   [2] http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/8197
   [3] http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/8865

These patches (created entirely by Thomas) would allow me to write
description (dts) that should cover what mach-trats.c did.

However, due to ongoing irqdomain and related changes I assume this
might take a while.

Thomas, may I ask about your plans wrt to irqdomains and wakeup/eints
(this [2] patchset)?

I am in the process of converting max8997, wake-interrupts and
interrupt combiner to the updated irqdomains support posted by Grant
Likely. I will be working on the updated patches for this in the next
week.

Thanks,
Thomas.
