numa, cpumask: move numa_node_id default implementation to topology.h, fix
Impact: build fix for powerpc and sparc
Today's linux-next build (powerpc allyesconfig) failed like this:
> In file included from include/linux/mmzone.h:776,
> from include/linux/gfp.h:5,
> from include/linux/kmod.h:23,

> from init/version.c:11:
> arch/powerpc/include/asm/mmzone.h:32: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'numa_cpumask_lookup_table'
Caused by commit 082edb7bf443eb8eda15b482d16ad9dd8137ad24 ("numa,
cpumask: move numa_node_id default implementation to topology.h") from
the cpus4096 tree which removed the include of linux/topology.h from
linux/mmzone.h.
Same for sparc64 defconfig.

Thanks for helpful advices.
This patch adds an option to drivers/ide/Kconfig and adds
some lines to drivers/ide/pmac.c . Now the driver checks
if the model is prefixed with "PowerBook" and the entire hack
can be toggled in the Kconfig.
Again, the patch is against linux 2.6.28.8.
Best regards,
TOMARI Hisanobu
p.s. oddly, the drive works in ATA/100 mode under untouched
MacOS X 10.5.

* [PATCH v2 1/3] powerpc/pci: Default to dma_direct_ops for pci dma_ops
From: Kumar Gala @ 2009-03-19 13:40 UTC (permalink / raw)
Cc: linuxppc-dev, Becky Bruce
This will allow us to remove the ppc32 specific checks in get_dma_ops()
that defaults to dma_direct_ops if the archdata is NULL. We really
should always have archdata set to something going forward.

Now that we set archdata for of_platform and platform devices via
platform_notify() we no longer need to special case having a NULL device
pointer or NULL archdata. It should be a driver error if this condition
shows up and the driver should be fixed.

* [PATCH v2 2/3] powerpc: setup default archdata for {of_}platform via bus_register_notifier
From: Kumar Gala @ 2009-03-19 13:40 UTC (permalink / raw)
Cc: linuxppc-dev, Becky Bruce
In-Reply-To: <1237470052-4071-1-git-send-email-galak@kernel.crashing.org>
Since a number of powerpc chips are SoCs we end up having dma-able
devices that are registered as platform or of_platform devices. We need
to hook the archdata to setup proper dma_ops for these devices.
Rather than having to add a bus_notify to each platform we add a default
one at the highest priority (called first) to set the default dma_ops for
of_platform and platform devices to dma_direct_ops. This allows platform
code to override the ops by providing their own notifier call back.
In the future to enable >4G DMA support on ppc32 we can hook swiotlb ops.

I think it would be better to make it a kernel command line option
instead of Kconfig knob.
The reason is: with distro (pre-compiled) kernels you don't have to
re-compile anything to make the drive work.
The other option is to enable BLK_DEV_IDE_PMAC_SHORTCABLE by default,
but I'm not sure if it's safe thing to do (most probably not).
Thanks for you work on this,

Long ago we had some code that actually used the CTR in the SW TLB
miss handlers (603/e300). Since we don't use it no reason to waste
cycles saving it off and restoring it (we actually didn't restore it
in the fast path case).

Now that r0 is free we can keep the value of I/DMISS in r3 and not reload
it before doing the tlbli/d. This saves us a few cycles in the fast path
case.

* [PATCH 3/3] powerpc/mm: e300c2/c3/c4 TLB errata workaround
From: Kumar Gala @ 2009-03-19 13:55 UTC (permalink / raw)
Cc: linuxppc-dev
In-Reply-To: <1237470941-23418-2-git-send-email-galak@kernel.crashing.org>
Complete workaround for DTLB errata in e300c2/c3/c4 processors.
Due to the bug, the hardware-implemented LRU algorythm always goes to way
1 of the TLB. This fix implements the proposed software workaround in
form of a LRW table for chosing the TLB-way.
Based on patch from David Jander <david@protonic.nl>
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* PCI resource allocation in linux 2.6.27
From: Eduard Fuchs @ 2009-03-19 14:38 UTC (permalink / raw)
To: linuxppc-dev
Hi,
i'm porting the linux 2.6.27 kernel to the custom board with PowerPC 7448 &
Marvell 64560. In DTS file the PCI ranges are configured as follows:
system-controller@fbe00000 { /* Marvell Discovery mv64560 (Discovery V)*/
#address-cells = <1>;
#size-cells = <1>;
model = "mv64560"; /* Default */
compatible = "marvell,mv64360", "marvell,mv64560";
clock-frequency = <133333333>;
reg = <0xfbe00000 0x100000>;
virtual-reg = <0xfbe00000>;
ranges =
<0xd8000000 0xd8000000 0x00010000 /* PCI 0 I/O Space */
0x80000000 0x80000000 0x68000000 /* PCI 0 MEM Space */
0xd8080000 0xd8080000 0x00010000 /* PCI 1 I/O Space */
0x60000000 0x60000000 0x20000000 /* PCI 1 MEM Space */
0x00000000 0xfbe00000 0x00100000>; /* Bridge's regs */
.....
PCI0: pci@30000 {
#address-cells = <3>;
#size-cells = <2>;
#interrupt-cells = <1>;
device_type = "pci";
compatible = "marvell,mv64360-pci";
reg = <0x30c78 12>;
ranges =
<0x01000000 0x0 0x00000000 0xd8000000 0x0 0x00010000
0x02000000 0x0 0x80000000 0x80000000 0x0 0x40000000>;
bus-range = <0 255>;
clock-frequency = <33000000>;
interrupt-pci-iack = <0x30c34>;
interrupt-parent = <&PIC>;
interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
interrupt-map = <
/* IDSEL 0x07 */
0x3800 0 0 1 &PIC 74
0x3800 0 0 2 &PIC 74
0x3800 0 0 3 &PIC 74
0x3800 0 0 4 &PIC 74
/* IDSEL 0x09 */
0x4800 0 0 1 &PIC 68
0x4800 0 0 2 &PIC 68
0x4800 0 0 3 &PIC 68
0x4800 0 0 4 &PIC 68
/* IDSEL 0x0A */
0x5000 0 0 1 &PIC 69
0x5000 0 0 2 &PIC 69
0x5000 0 0 3 &PIC 69
0x5000 0 0 4 &PIC 69
>;
};
when the kernel is booting, at the beginning the ranges are detected
correctly:
PCI host bridge /system-controller@fbe00000/pci@30000 (primary) ranges:
IO 0x00000000d8000000..0x00000000d800ffff -> 0x0000000000000000
MEM 0x0000000080000000..0x00000000bfffffff -> 0x0000000080000000
nevertheless later the range for IO space is changed as follow:
PCI: Probing PCI hardware
....
PCI: PHB (bus 0) bridge rsrc 0: 0000000000011000-0000000000020fff [0x100],
PCI: PHB (bus 0) bridge rsrc 1: 0000000080000000-00000000bfffffff [0x200],
normally the IO space should be from 0x00000000-0x0000ffff. Can someone
explain to me where the offset 0x11000 comes from.
Best regards
Eduard Fuchs

* [PATCH v2 2/5] NAND: FSL-UPM: add support for selecting chips via MAR
From: Wolfgang Grandegger @ 2009-03-19 15:16 UTC (permalink / raw)
To: linux-mtd, linuxppc-dev
In-Reply-To: <1237475768-11481-2-git-send-email-wg@grandegger.com>
For the NAND chips on the TQM8548 modules, a special chip-select logic is
used. It uses dedicated address lines to be set via UPM machine address
register (mar). This patch also adds that support to the FSL-UPM driver.

* [PATCH v2 3/5] NAND: FSL-UPM: Add wait flags to support board/chip specific delays
From: Wolfgang Grandegger @ 2009-03-19 15:16 UTC (permalink / raw)
To: linux-mtd, linuxppc-dev
In-Reply-To: <1237475768-11481-3-git-send-email-wg@grandegger.com>
The NAND flash on the TQM8548_BE modules requires a short delay after
running the UPM pattern. The TQM8548_BE requires a further short delay
after writing out a buffer. Normally the R/B pin should be checked, but
it's not connected on the TQM8548_BE. The existing driver uses similar
fixed delay points. To manage these extra delays in a more general way,
I introduced the "wait-flags" property allowing the board-specific driver
to specify various types of extra delay.

* powerpc/85xx: Add support for the "socrates" board (MPC8544)
From: Wolfgang Grandegger @ 2009-03-19 15:26 UTC (permalink / raw)
To: linuxppc-dev
This patch adds support for the "socrates" board based on the MPC8544.
Supported are Ethernet, serial console, I2C, I2C-based RTC and
temperature sensors, NOR and NAND flash, PCI, USB, CAN and Lime
display controller.
The multiplexing of FPGA interrupts onto PowerPC interrupt lines is
supported through our own fpga_pic interrupt controller driver.
For example the SJA1000 controller is level low sensitive connected to
fpga_pic line 2 and is routed to the second (of three) irq lines to
the CPU:
can@3,100 {
compatible = "philips,sja1000";
reg = <3 0x100 0x80>;
interrupts = <2 2>;
interrupts = <2 8 1>; // number, type, routing
interrupt-parent = <&fpga_pic>;
};

* [PATCH -next] fsl_pq_mdio: Revive Gianfar TBI PHY support
From: Anton Vorontsov @ 2009-03-19 15:52 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Andy Fleming, linuxppc-dev
commit 1577ecef766650a57fceb171acee2b13cbfaf1d3 ("netdev: Merge UCC
and gianfar MDIO bus drivers") broke the TSEC TBI PHY support: the
driver now refuses to probe TBI MDIO buses as it doesn't know about
"fsl,gianfar-tbi" compatible entry, and thus _probe() fails with
-ENODEV status.
Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar
MDIO buses.

However, the code should treat "mem" as "standby" on chips that don't
support deep sleep. What does the device tree look like (the upstream
device tree for that board does not have any reference to the PMC)? What
kernel are you using?

This needs to be:
return __pte(((pte_basic_t)(pfn) << PTE_RPN_SHIFT) |
pgprot_val(pgprot)); }
Otherwise on ppc32 w/36-bit physical we lose the upper bits of the pfn.

Can you tell more about which kernel you are using?
Please use the lates git head called "ads5121" from denx.
I am using that one, and the UART works fine.
There are although a lot of tricky details in your device-tree that have to
be correct in order for this driver to work.
Are you using you own hardware, or are you using the ADS5121?
What version of the MPC5121e processor do you have? M34K, 2M34K or M36P?

* [PATCH -next] fsl_pq_mdio: Use proper address translation
From: Anton Vorontsov @ 2009-03-19 16:48 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Andy Fleming, linuxppc-dev
Currently the driver just read "reg" property for constructing MDIO
bus IDs, but this won't work when we'll start using "ranges = <>" in
the device tree, so this will pop up:
Freescale PowerQUICC MII Bus: probed

This patch fixes the issue by translating the "reg" property to a full
address, and thus avoids the duplicate names.
