  ARM: bcm: fix missing include of kona_l2_cache.h (2016-06-08 10:17:15 -0700)

----------------------------------------------------------------
This pull request contains SoC changes for Broadcom ARM-based SoCs:

- Chris prepares support for the BCM23550 by removing reset code in the
  BCM21664 machine code since a proper drivers/power/reset driver is provided and
  shared, he then adds a machine entry point for BCM23550 and updates the SMP
  code to bring-up the secondary cores on BCM23550

- Ben fixes a warning in the Kona L2 SMC code by adding the missing include file

  ARM: Remove bcm_defconfig (2016-06-16 13:40:49 -0700)

----------------------------------------------------------------
This pull request contains defconfig changes for Broadcom ARM-based SoCs:

- Florian enables support for the BCM63xx DSL SoCs basic peripherals, enables
  the networking subsystems for Set Top Box SoCs, enables the PWM, watchdog and
  the AHCI controller and SATA PHY drivers

- Florian removes the bcm_defconfig file which is no longer useful and updates
  multi_v7_defconfig to include the Kona watchdog to provide proper reboot for the
  Broadcom Kona platforms

Please note that Tejun Heo has queued a patch which renames AHCI_BRCMSTB into
AHCI_BRCM, to avoid two patches in a row, we just enable AHCI_BRCM to be future
proof

Is bcm-kernel-feedback-list at broadcom.com a list that the public can subscribe
to, or is it an internal list that the team is on?

If it's the latter then it shouldn't be a mailing list in the maintainers
file. There's a dual purpose to the L: entries -- one is where to cc the
patches to, the other is what list to figure out how to subscribe to if you
care about patches for that platform...


Not merged until the above is clarified.

So, you say that bcm_defconfig is no longer useful. While I'm happy to see the
number of defconfigs go down, I'd like to clarify that we do still see per-SoC
defconfigs somewhat useful, in that they are a lot closer to what someone would
want to use for defconfig in a product kernel based on the SoC. It's easier to
start from the SoC-specific defconfig and remove pieces that aren't needed than
to start from multi_v7_defconfig.

That being said, I'm happy to remove it if you think that's what works best for
your platform.

Merged into next/defconfig.

I was asked by Florian to add bcm-kernel-feedback-list@ but indeed he
didn't specify if this should be L: entry.

bcm-kernel-feedback-list at broadcom.com in the MAINTAINERS file for

I think M: is better, we have a couple of examples like that (x86 at kernel.org,
Dept-GELinuxNICDev at qlogic.com, linux-wimax at intel.com, ...).

Yep, having it as a M: entry would be fine with me as well. Please
respin the patch/branch -- we can apply a patch directly instead of
doing a merge if that's easier for you.

If M: is supposed to be used for bcm-kernel-feedback-list then a new 
patch applied to multiple locations in the MAINTAINERS file would solve 
the problem.

I completely agree that per-SoC defconfigs are extremely useful. I 
attempted to do so for Cygnus and would like to for other Broadcom SoCs 
as well. Unfortunately Arnd's policy was one defconfig per company. This 
prevents use from doing so. Broadcom has a variety of SoCs and families. 
Some share technology, others are entirely different. On the projects I 
work with we don't use multi_v7_defconfig nor do our customers. We use 
per SoC defconfigs.

So, as it stands bcm_defconfig is of little use to us. We are able to 
upstream everything into the kernel except for the defconfig file. We 
are forced to maintain these internally. Yet we are able to upstream dts 
files which are per board...

I really think the job of building an appropriate .config file for your
platform belongs in the build system you are utilizing. There could be
user-visible option that you allow people to turn on/off (e.g: kernels'
frace along with user-space profiling tools etc.), and in general build
systems enable a bunch of generic options shared across all targets they
support, and they just maintain relevant fragments for the specific
targets you build for, making the defconfig more or less contained
within the build system, and under control.

Maintaining a defconfig file is both boring and a great deal of pain
when trying to resolve conflicts, and keep in mind that the upstream
community can nitpick on every single change you enable/disable in there ;)

Yeah, I'm with Arnd on this in general; we can't do a crazy number of
defconfigs -- which is why I said it's a starting point for further
paring down. Still, given the variety of platforms from Broadcom it's
likely too broad to be useful. Removing it makes sense.

There's a huge difference in the cost of carrying a defconfig vs a dts
file. A dts file is very cheap to compile and carry, while each
defconfig adds a significant amount of time spent on build coverage.

I have been attempting to add Kconfig defaults to new drivers we are 
upstreaming.  That way if a driver is used for an SoC family you simply 
can select the SoC family and voila the drivers are all default selected 
for you.  An added benefit is we don't need to submit patches for 
multi_v7_defconfig every time we upstream a new driver.  The drivers are 
automatically selected via the Kconfig.  If this was promoted in the 
Kconfig files then all the other SoC specific defconfig files could be 
removed.  All information about the SoC would be contained in the kernel 
instead of being maintained elsewhere.  The user could generate any 
defconfig for their specific SoC(s) and the only paring down to be done 
would be limited to removing drivers that they don't use on their 
specific SoC.  I have not added defaults for existing drivers - but if 
acceptable may do so at some time.  This may make a long list of 
defaults for popular drivers, but it makes things far more maintainable 
than multiple defconfigs or burying SoC kernel specifics in a build system.

Perhaps the build coverage should only be for multi_v7_defconfig and a 
big endian build version of it?
