Subject: [PATCH] powerpc: Add CONFIG_DEFAULT_UIMAGE to build a uImage by
 default for a board

Embedded boards that u-boot require a kernel image in the uImage format.
This allows a given board to specify it wants a uImage built by default.

Subject: [PATCH] powerpc: generalize PPC44x_PIN_SIZE

The following patch generalizes PPC44x_PIN_SIZE by changing it to
PPC_PIN_SIZE, which can be defined by any sub-arch to automatically adjust
VMALLOC_START.

Define PPC_PIN_SIZE on 8xx, avoiding potential conflicts with the
pinned space.

Subject: [PATCH] PPC32 8xx: support for the physmapped flash on m8xx

Implemented more correct way to support physmapped flash on m8xx
than map in mtd.

The areas intended to contain bootloader are protected readonly.
Note that CFI and JEDEC stuff should be configured properly in order
this to work, e.g. for 885/86x CFI should support 4-chip flash interleave.
Also fixed compilation warning.

Subject: [PATCH] powerpc: Move xparameters.h into xilinx virtex device
 specific path

xparameters should not be needed by anything but virtex platform code.
Move it from include/asm-ppc/ to platforms/4xx/xparameters/

This is preparing for work to remove xparameters from the dependancy tree
for most c files.  xparam changes should not cause a recompile of the world.
Instead, drivers should get device info from the platform bus (populated
by the boot code)

Subject: [PATCH] powerpc: Make Virtex-II Pro support generic for all Virtex
 devices

The PPC405 hard core is used in both the Virtex-II Pro and Virtex 4 FX
FPGAs.  This patch cleans up the Virtex naming convention to reflect more
than just the Virtex-II Pro.

Rename files virtex-ii_pro.[ch] to virtex.[ch]
Rename config value VIRTEX_II_PRO to XILINX_VIRTEX

From 1a42e53d175074f340a3f85042ed64cfc51be216 Mon Sep 17 00:00:00 2001
From: "Grant C. Likely" <grant.likely@secretlab.ca>
Date: Thu, 19 Jan 2006 01:12:48 -0700
Subject: [PATCH] powerpc: Migrate Xilinx Vertex support from the OCP bus to
 the platfom bus.

This patch only deals with the serial port definitions as there is no
support for any other xilinx IP cores in the kernel tree at the moment.

Board specific configuration moved out of virtex.[ch] and into the
xparameters.h wrapper.

This also prepares for the transition to the flattened device tree model.
When the bootloader provides a device tree generated from an xparameters.h
files, the kernel will no longer need xparameters/*.  The platform bus will
get populated with data from the device tree, and the device drivers will
be automatically connected to the devices.  Only the bootloader (or
ppcboot) will need xparameters directly.

From 42dc75c4b97922d3d7707ac0b097fbeeca20b108 Mon Sep 17 00:00:00 2001
From: Vitaly Bordug <vbordug@ru.mvista.com>
Date: Fri, 20 Jan 2006 22:22:36 +0300
Subject: [PATCH] ppc32: MPC885ADS, MPC866ADS and MPC8272ADS-specific platform
 stuff for fs_enet

Added proper ppc_sys identification and fs_platform_info's for MPC 885ADS,
866ADS and 8272ADS, utilizing function assignment to remove/do not use
platform devices which conflict with PD-incompatible drivers.

Subject: [PATCH] powerpc: Always panic if lmb_alloc() fails

Currently most callers of lmb_alloc() don't check if it worked or not, if it
ever does weird bad things will probably happen. The few callers who do check
just panic or BUG_ON.

So make lmb_alloc() panic internally, to catch bugs at the source. The few
callers who did check the result no longer need to.

The only caller that did anything interesting with the return result was
careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic
automatically, a little messy, but passable.

Subject: [PATCH] powerpc: Fix Kernel FP unavail exception for BookE

Updated FP unavailable exception to refer to the correct
function in traps.c. head_booke.h was using the old name, KernelFP,
instead of kernel_fp_unavailable_exception.

Cut-and-paste from the old platform code in arch/ppc resulted in
arch/powerpc/platforms/85xx/mpc85xx_ads.c having way too many
header files included.  Clean this up.

Rename mpc85xx.c to misc.c to match the pattern established by the
8349 port - consistency is a good thing.  Also run Lindent on the

From 75288c78c69020a574d93770c3a941b785f3d93d Mon Sep 17 00:00:00 2001
From: Vitaly Bordug <vbordug@ru.mvista.com>
Date: Fri, 20 Jan 2006 22:22:34 +0300
Subject: [PATCH] ppc32: Make platform devices being able to assign functions

Implemented by  modification of the .name field of the platform device,
when PDs with the
same names are to be used within different drivers, as
<device_name> -> <device_name>:<function>
Corresponding drivers should change the .name in struct device_driver to
reflect upper of course.

Added ppc_sys_device_disable/enable function set, making it easier to
disable all the inexistent/not utilized platform device way pdevs. By the
check of the "disabled" bit in the config field of ppc_sys_specs, disabled
platform devices will be either added/removed from the bus, or simply not
registered on it, depending on the time when disable/enable call asserted.

The default behaviour when nothing is disabled/enabled will be "all devices
are enabled", which is the same as before.

Also helper platform_notify_map function added, making assignment of
board-specific platform_info more consistent and generic.

Subject: [PATCH] powerpc: trivial: modify comments to refer to new location of
 files

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

Subject: [PATCH] powerpc: Add missing vmlinux.bin target

With this patch 'make vmlinux.bin' works.  This is needed by
some embedded platforms.  Kumar already added the routines
to actually build the image in arch/powerpc/boot/Makefile.

Subject: powerpc: Implement accurate task and CPU time accounting

This implements accurate task and cpu time accounting for 64-bit
powerpc kernels.  Instead of accounting a whole jiffy of time to a
task on a timer interrupt because that task happened to be running at
the time, we now account time in units of timebase ticks according to
the actual time spent by the task in user mode and kernel mode.  We
also count the time spent processing hardware and software interrupts
accurately.  This is conditional on CONFIG_VIRT_CPU_ACCOUNTING.  If
that is not set, we do tick-based approximate accounting as before.

To get this accurate information, we read either the PURR (processor
utilization of resources register) on POWER5 machines, or the timebase
on other machines on

* each entry to the kernel from usermode
* each exit to usermode
* transitions between process context, hard irq context and soft irq
  context in kernel mode
* context switches.

On POWER5 systems with shared-processor logical partitioning we also
read both the PURR and the timebase at each timer interrupt and
context switch in order to determine how much time has been taken by
the hypervisor to run other partitions ("steal" time).  Unfortunately,
since we need values of the PURR on both threads at the same time to
accurately calculate the steal time, and since we can only calculate
steal time on a per-core basis, the apportioning of the steal time
between idle time (time which we ceded to the hypervisor in the idle
loop) and actual stolen time is somewhat approximate at the moment.

This is all based quite heavily on what s390 does, and it uses the
generic interfaces that were added by the s390 developers,
i.e. account_system_time(), account_user_time(), etc.

This patch doesn't add any new interfaces between the kernel and
userspace, and doesn't change the units in which time is reported to
userspace by things such as /proc/stat, /proc/<pid>/stat, getrusage(),
times(), etc.  Internally the various task and cpu times are stored in
timebase units, but they are converted to USER_HZ units (1/100th of a
second) when reported to userspace.  Some precision is therefore lost
but there should not be any accumulating error, since the internal
accumulation is at full precision.

Subject: [PATCH] powerpc: Better pmd_bad() and pud_bad() checks

At present, the powerpc pmd_bad() and pud_bad() macros return false
unless the given pmd or pud is zero.  This patch makes these tests
more thorough, checking if the given pmd or pud looks like a plausible
pte page or pmd page pointer respectively.  This can result in helpful
error messages when messing with the pagetable code.

Subject: [PATCH] powerpc: add for_each_node_by_foo helpers

Typical use for of_find_node_by_name and of_find_node_by_type is to
iterate over all nodes of a given type/name.  Add a helper macro to
do that (in spirit of the list_for_each* macros).

Subject: [PATCH] ppc: Fix platform_notify functions marked __init

While adding USB support to an MV64360 based board this week, I
discovered that all MV64x60 boards in the kernel have platform_notify
functions marked with __init. This causes an oops if a device is added
after boot.

The patch below removes the __init markers. I do not have all these
boards to test on, but the change seems very unlikely to break anything
else.

later, after all nodes have been set online.

Code to handle Power4's invalid node id (0xffff) is duplicated for cpu
and memory.  Better to handle this case in one place --
of_node_to_nid.  Overall behavior should be unchanged.

Subject: [PATCH] powerpc numa: Support sparse online node map

The powerpc numa code unconditionally onlines all nodes from 0 to the
highest node id found, regardless of whether cpus or memory are
present in the nodes.  This wastes 8K per node and complicates some
cpu and memory hotplug situations, such as adding a resource that
doesn't map to one of the nodes discovered at boot.

Set nodes online as resources are scanned.  Fall back to node 0 only
when we're sure this isn't a NUMA machine.

Instead of defaulting to node 0 for cases of hot-adding a resource
which doesn't belong to any initialized node, assign it to the first
online node.

We can plug the boot cpu into its node independently of whether numa
topology is detected.  And numa_setup_cpu does the right thing for all
cases now, so remove special-casing for non-numa from the cpu hotplug
callback.

Subject: [PATCH] powerpc: Unconfuse htab_bolt_mapping() callers

htab_bolt_mapping() takes a vstart and pstart parameter, but all but one of
its callers actually pass it vstart and vstart. Luckily before it passes
paddr (calculated from paddr) to the hpte_insert routines it calls
virt_to_abs() (aka. __pa()) on the address, so there isn't actually a bug.

map_io_page() however does pass pstart properly, so currently it's broken
AFAICT because we're calling __pa(paddr) which will get us something very
large. Presumably no one's calling map_io_page() in the right context.

Anyway, change htab_bolt_mapping() callers to properly pass pstart, and then
use it properly in htab_bolt_mapping(), ie. don't call __pa() on it again.

Booted on p5 LPAR, iSeries and Power3.

do it now in iommu_init_early_pSeries().

Subject: [PATCH] powerpc: Replace platform_is_lpar() with a firmware feature

It has been decreed that platform numbers are evil, so as a step in that
direction, replace platform_is_lpar() with a FW_FEATURE_LPAR bit.

Currently FW_FEATURE_LPAR really means i/pSeries LPAR, in the future we might
have to clean that up if we need to be more specific about what LPAR actually
means. But that's another patch ...

Subject: [PATCH] powerpc: iseries: mf related cleanups

Some cleanups in the iSeries code.
 - Make mf_display_progress() check mf_initialized rather than the caller.
 - Set mf_initialized in mf_init() rather than in setup.c
 - Then move mf_initialized into mf.c, the only place it's used.
 - Move the mf related logic from iSeries_progress() to mf_display_progress()
 - Use a #define to size the pending_event_prealloc array
 - Use that define in the initialsation loop rather than sizeof jiggery pokery
 - Remove stupid comment(s)
 - Mark stuff static and/or __init

at the mf routines. We need to pass the cmd through to mf_reboot to make it
work, but that seems reasonable.

Subject: [PATCH] powerpc: iseries: Make more stuff static in
 platforms/iseries/mf.c

Make mf_get_rtc(), mf_get_boot_rtc() and mf_set_rtc() static, cause they can
be. We need to move mf_set_rtc() to avoid a forward declaration.

Subject: [PATCH] powerpc: Remove calculation of io hole

In mm_init_ppc64() we calculate the location of the "IO hole", but then
no one ever looks at the value. So don't bother.

That's actually all mm_init_ppc64() does, so get rid of it too.

Now powerpc uses the generic RTC stuff we should not enable the old RTC.
Doing so will result in hangs at boot.

Remove the assumption that driver_register() returns the number of devices
bound to the driver.  In fact, it returns zero for success or a negative
error value.

Nobody uses the return value of of_register_driver() anyway.

All callers of macio_register_driver() either ignore the return value or
