      Add support for generic BCM SoC chipsets · 8ac49e04
      由 Christian Daudt 提交于 
      In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.

v2 patch mods
--------
 - Remove l2x0_of_init call as there were problems with the code.
   A separate patch will be submitted with cache init code
 - Rename capri files and refs to bcm281xx-based names
 - Add bcm281xx binding doc
 - various misc cleanups

v3 patch mods
-------------
 - Remove extra #include lines
 - Remove remaining references to capri
 - dt uart chipset string added
 - cleaned up chip # references

v4 patch mods
-------------
 - swap order of compatible definitions for uart
 - fix typo

v5 patch mods
-------------
 - Rename bcm281xx to bcm11351 in dts+code,
   leaving references to bcm281xx only in help+comments.

v6 patch mods
-------------
 - fix typo in uart 'compatible' string

      ARM: plat-nomadik: move MTU, kill plat-nomadik · 694e33a7
      由 Linus Walleij 提交于 
      This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.

As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.

After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

      zynq: remove use of CLKDEV_LOOKUP · f7977939
      由 Josh Cartwright 提交于 
      The Zynq support in mainline does not (yet) make use of any of the
generic clk or clk lookup functionality.  Remove what is upstream for
now, until the out-of-tree implementation is in suitable form for
merging.

An important side effect of this patch is that it allows the building of
a Zynq kernel without running into unresolved symbol problems:

   drivers/built-in.o: In function `amba_get_enable_pclk':
   clkdev.c:(.text+0x444): undefined reference to `clk_enable'
   drivers/built-in.o: In function `amba_remove':

   make[2]: *** [vmlinux] Error 1
   make[1]: *** [sub-make] Error 2
   make: *** [all] Error 2

In addition, eliminate Zynq's "use" of the versatile platform, as it is
no longer needed.  As Nick Bowler points out:

   For the record, I think this was introduced by commit 56a34b03
   ("ARM: versatile: Make plat-versatile clock optional") which forgot to
   select PLAT_VERSATILE_CLOCK on Zynq.  This is not all that surprising,
   because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in
   the Makefile.

   Nevertheless, the only feature from versatile that Zynq needed was the
   clock support, so this patch should *also* delete the secret use of
   plat-versatile by removing this line from arch/arm/Makefile:

      plat-$(CONFIG_ARCH_ZYNQ)      += versatile

      ARM: pass -marm to gcc by default for both C and assembler · 91802a8e
      由 Arnd Bergmann 提交于 
      The Linaro cross toolchain and probably others nowadays default to
building in THUMB2 mode. When building a kernel for a CPU that does
not support THUMB2, the compiler complains about incorrect flags.
We can work around this by setting -marm for all non-T2 builds.

-marm was passed unconditionally for C files previously, but nothing was
passed to the gcc frontend when processing .S files, resulting in a
warning.  The assembler never defaults to ARM unless -Wa,-mthumb is
supplied explicitly, so the files were still assembled correctly.

This patch makes sure that -marm is passed for .S files too, and also
avoids the redundant gcc -marm -mthumb in Thumb kernels.

Without this patch, building assabet_defconfig results in:

usr/initramfs_data.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default]
arch/arm/nwfpe/entry.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default]

      ARM: initial multiplatform support · 387798b3
      由 Rob Herring 提交于 
      This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:

* SMP support must be turned off because of conflicting symbols.
  Marc Zyngier has proposed a solution by adding a new SOC
  operations structure to hold indirect function pointers
  for these, but that work is currently stalled

* We turn on SPARSE_IRQ unconditionally, which is not supported
  on most platforms. Each of them is currently in a different
  state, but most are being worked on.

* A common clock framework is in place since v3.4 but not yet
  being used. Work on this is on its way.

* DEBUG_LL for early debugging is currently disabled.

* THUMB2_KERNEL does not work with allyesconfig because the
  kernel gets too big

[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.

      ARM: 7420/1: Improve build environment isolation · bcccc50c
      由 Vincent Sanders 提交于 
      Increasingly distributions are setting default build environments to
have LDFLAGS with hardening options. There seems to be an assumption
with those options that LDFLAGS are passed to the compiler frontend
rather than used directly with ld (which the kernel build process
assumes)

To prevent build failures in such environments this patch changes the
ARM architecture Makefile to override the LDFLAGS from the environment
similar to the behaviour on other common architectures e.g. x86

      ARM: remove ixp23xx and ixp2000 platforms · c65f2abf
      由 Rob Herring 提交于 
      ixp2xxx platforms have had no real changes since ~2006 and the maintainer
has said on irc that they can be removed:

13:05 < nico> do you still care about ixp2000?
13:22 < lennert> not really, no
13:58 < nico> do you think we could remove it from the kernel tree?
14:01 < lennert> go for it, and remove ixp23xx too while you're at it

Removing will help simplify ARM consolidation in general and PCI re-work
specifically.
