[GIT PULL] ARM: brcmstb: SMP, Kconfig, earlyprintk and GISB fixes

[Florian Fainelli]

These changes were posted late during the v3.18 release cycle, and were
eventually added to your 'late' branch, but here is an updated version

Thanks!

  bus: brcmstb_gisb: save and restore GISB timeout (2014-10-20 12:44:42 -0700)

----------------------------------------------------------------
This pull request contains 3 changes for the brcmstb platform and 2 changes
to the GISB bus arbiter driver

- fist patch adds earlyprintk to brcmstb platforms using the existing 8250
  infrastructure

- second patch re-introduces SMP support after fixing the problems we had in
  the initial implementation, for this patch to apply cleanly, I had to advance
  up to "ARM: brcmstb: revert SMP support"

- third patch is dropping unused Kconfig dependencies

- fourth patch registers the ARM fault code for external aborts that the GISB
  bus arbiter driver is designed to assit

- fifth patch does save/restore the GISB arbiter timeout across S3
  suspend/resume cycles

Thanks!

I assume the contents are all still good. Please make sure you address
them correctly. You have sent a pull request 'To' the mailing list.
If you want us to pick them up into arm-soc, please send it 'To'
arm at kernel.org, 'Cc' linux-arm-kernel at lists.infradead.org so it
doesn't get lost.

Not pulling this at the moment as I'm still busy catching up with
email after last week's conference. If you send it to the right list,
we'll get to it soon.

Yes, that was a mistake, I actually send a second pull request with all
the usual email addresses including those you mention.

Forgive me if I'm being dense, but I don't see these changes in
linux-next, and I only see a portion of them in arm-soc/brcmstb/smp-uart
(plus, they're old, so there are merge conflicts). Did these get
overlooked?

Not overlooked, we're just running way behind on merges.

I'll do a sweep today/tonight and start doing merges. I normally do it
chronologically though and there are even older ones to take care of.
I'll get to this quickly I hope.

I believe the changes Brian refers to is your merge of our 3.18 pull
request in your 'late' branch, these changes are now superseded by this
exact pull request we are discussing right now, which is intended for
3.19 (hope this clears things out).

Ok, actually looking at the pull request now, sorry for the delay.

Looks like the two patches fromy ou should have been in a drivers branch
instead. Since they were trivial I'll keep them in here though.
