      powerpc: Delete old PrPMC 280/2800 support · 3c8464a9
      由 Paul Gortmaker 提交于 
      This processor/memory module was mostly used on ATCA blades and
before that, on cPCI blades.  It wasn't really user friendly, with
custom non u-boot bootloaders (powerboot/motload) and no real way
to recover corrupted boot flash (which was a common problem).

As such, it had its day back before the big ppc --> powerpc move
to device trees, and that was largely through commercial BSPs that
started to dry up around 2007.

Systems using one were largely in a "deploy and sustain" mode,
so interest in upgrading to new kernels in the field was nil.
Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA
chassis largely rules out any hobbyist/enthusiast interest.

The point of all this, is that we might as well delete the in
kernel files relating to this platform.  No point in continuing
to build it via walking the defconfigs or via linux-next testing.

      powerpc/embedded6xx: Add support for Motorola/Emerson MVME5100 · be201981
      由 Stephen Chivers 提交于 
      Add support for the Motorola/Emerson MVME5100 Single Board Computer.

The MVME5100 is a 6U form factor VME64 computer with:

	- A single MPC7410 or MPC750 CPU
	- A HAWK Processor Host Bridge (CPU to PCI) and
	  MultiProcessor Interrupt Controller (MPIC)
	- Up to 500Mb of onboard memory
	- A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip
	- Two 16550 compatible UARTS
	- Two Intel E100 Fast Ethernets
	- Two PCI Mezzanine Card (PMC) Slots
	- PPCBug Firmware

The HAWK PHB/MPIC is compatible with the MPC10x devices.

There is no onboard disk support. This is usually provided by installing a PMC
in first PMC slot.

This patch revives the board support, it was present in early 2.6
series kernels. The board support in those days was by Matt Porter of
MontaVista Software.

CSC Australia has around 31 of these boards in service. The kernel in use
for the boards is based on 2.6.31. The boards are operated without disks
from a file server.

This patch is based on linux-3.13-rc2 and has been boot tested.

Only boards with 512 Mb of memory are known to work.

      Kbuild: Use dtc's -d (dependency) option · 7c431851
      由 Stephen Warren 提交于 
      This hooks dtc into Kbuild's dependency system.

Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
lack of this feature recently caused me to have very confusing "git
bisect" results.

For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

      powerpc: Add support for OpenBlockS 600 · 11eab297
      由 Benjamin Herrenschmidt 提交于 
      So I've had one of these for a while and it looks like the vendor never
bothered submitting the support upstream.

This adds it using ppc40x_simple and provides a device-tree.

There are some changes to the boot wrapper because the way u-boot works
on this thing, it seems to expect a multipart image with the kernel,
initrd and dtb in it.

The USB support is missing as it needs the yet unmerged driver for
the DWC OTG part and the GPIOs may need further definition in the dts.

      zlib: Fix build of powerpc boot wrapper · 6846ee5c
      由 Benjamin Herrenschmidt 提交于 
      Commit ac4c2a3b broke the build
of all powerpc boot wrappers.

It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.

We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.

It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).

This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.

This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

      Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc · 9fffb55f
      由 David Gibson 提交于 
      The powerpc kernel always requires an Open Firmware like device tree
to supply device information.  On systems without OF, this comes from
a flattened device tree blob.  This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel.  Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM).  To do this it uses the libfdt library.

Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).

However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs.  A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.

The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

      powerpc: Copy bootable images in the default install script · 29f1aff2
      由 Grant Likely 提交于 
      This patch makes the default install script (arch/powerpc/boot/install.sh)
copy the bootable image files into the install directory.  Before this
patch only the vmlinux image file was copied.

This patch makes the default 'make install' command useful for embedded
development when $(INSTALL_PATH) is set in the environment.

As a side effect, this patch changes the calling convention of the
install.sh script.  Instead of a single 5th parameter, the script is now
passed a list of all the target images stored in the $(image-y) Makefile
variable.  This should be backwards compatible with existing install scripts
since it just adds additional arguments and does not change existing ones.
