I wouldn't cause that usage valid :)

* [PATCH] powerpc: Fix zImage.coff on oldworld PowerMac
From: Benjamin Herrenschmidt @ 2006-10-03 4:27 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev list
Recent changes to the PowerPC zImage wrapper broke zImage.coff due to
the addition of new ELF sections that aren't very well converted to
xcoff and not supported by old OpenFirmware. This fixes it by putting
those sections in the xcoff .data.

* [PATCH 2/2] Fix xmon=off and cleanup xmon initialisation
From: Michael Ellerman @ 2006-10-03 4:12 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <1159848727.955823.82109451606.qpush@concordia>
My patch to make the early xmon logic work with earlier early param
parsing (480f6f35a149802a94ad5c1a2673ed6ec8d2c158) breaks xmon=off.
No one does this obviously as xmon rocks, but it should really work
as documented.
While fixing that it struck me that we could move the xmon param
handling into xmon.c, and also consolidate the
xmon_init()/do_early_xmon logic into xmon_setup(). This means
xmon=early drops into xmon a little earlier on 32-bit, but it
seems to work just fine.
Tested on PSERIES and CLASSIC32.

* [PATCH 1/2] Cleanup include/asm-powerpc/xmon.h
From: Michael Ellerman @ 2006-10-03 4:12 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
For some reason we have two prototypes for xmon_init(), remove the
one in system.h.
No one calls xmon() anymore, debugger() is preferable, so we don't
need the prototype. And similarly no one calls xmon_printf().
Also update the include guards on xmon.h to match the standard
format, add copyright and license, and add comments to #endifs.
Built for pseries_defconfig and pmac32_defconfig.

you should use cpu_relax(). Something like
while(in_be32(&qe_immr->cp.cecr) & QE_CR_FLG)
cpu_relax();

any reasons not to use out_be32? Also, why not doing this in a

Is get_bcsr() needed since you removed its use from ucc_geth? (if
not, let's remove it and the header as well).

Sorry, for some reason I thought isa_bus_to_virt and isa_virt_to_bus
were defined in terms of virt_to_bus/bus_to_virt instead of
virt_to_phys/phys_to_virt.

* [PATCH 2.2/7] Add QUICC Engine (QE) infrastructure
From: Kim Phillips @ 2006-10-03 2:07 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
From: Li Yang <leoli@freescale.com>
note: linuxppc-dev rejected patch 2/7, so I split 2/7 into two, of which this is the second and last.
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues

* [PATCH 2.1/7] Add QUICC Engine (QE) infrastructure
From: Kim Phillips @ 2006-10-03 2:07 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
From: Li Yang <leoli@freescale.com>
note: linuxppc-dev rejected patch 2/7, so I split 2/7 into two, of which this is the first. This patch only adds files in a new directory (arch/powerpc/sysdev/qe_lib) so as not to break git-bisect.
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues

You might want to convince Andrew accepting my patch to make
virt_to_bus/bus_to_virt give compile warnings on i386 for making
people more aware of this problem...

In case anyone is interested, the patch is below.

<-- snip -->
virt_to_bus/bus_to_virt are long deprecated, mark them as __deprecated
on i386.
Without such warnings people will never update their code and fix
the errors in PPC64 builds.
And yes, some of the drivers affected are maintained.
This also catches accidential additions of users for these functions
like a usage of bus_to_virt() in the infiniband code that was added in
2.6.17-rc1 (already removed).
This patch increases the number of warnings shown during builds, but it
seems worth including it at least in -mm for making people aware of this
issue.

virt_to_bus and bus_to_virt are old interfaces that have been
deprecated for, oh, at least 5 years now, and can't be implemented
sanely on machines with an IOMMU - which includes all 64-bit powerpc
machines.
Unless someone pops up and volunteers to fix those old drivers, which
is unlikely, the only solution is to fix the Kconfig files to prevent
them from being selected on platforms that don't have virt_to_bus and
bus_to_virt.

* [PATCH 6/7] Add initial support for the e300c2 core
From: Kim Phillips @ 2006-10-03 1:10 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
Add support for the Freescale e300c2 core found in the MPC832x processor line.
As far as initial kernel support is concerned, the e300c2 core is identical to the e300c1 found in the mpc834x, except that it's had its floating point unit chopped off.

* [PATCH 7/7] add support for the mpc832x mds board
From: Kim Phillips @ 2006-10-03 1:10 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
Add support for MPC832x MDS evaluation board.
This patch depends on the 8360+QE lib patches by Leo.
The MPC832x processors (MPC8323E, MPC8323, MPC8321E, MPC8321) sport the e300c2 core plus a QUICC Engine (QE). This patch adds support for the 832x MDS evaluation board.
The 832x MDS dts and defconfig files are pending more tests.

* [PATCH 3/7] ucc_geth driver fixes mostly as a result of QE lib changes
From: Kim Phillips @ 2006-10-03 1:09 UTC (permalink / raw)
To: netdev; +Cc: Mackerras, Paul, jgarzik, linuxppc-dev
From: Li Yang <leoli@freescale.com>
note: to be applied through the netdev tree
o Update the ucc_geth driver according to qe_lib changes.
o Fix l3qt bug.
o platform_device to of_device transition
o removed bcsr bit manipulation code
o removed typedefs
o uint -> u32 conversions
o replaced following define usages:
QE_SIZEOF_BD, UCC_GETH_SIZE_OF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR,
BD_BUFFER, BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o minor style fixups

+
+ Required properties:
+
+ - device_type : Should be "board-control"
+ - reg : Offset and length of the register set for the device
+
+ Example:
+
+ bcsr@f8000000 {

+ reg = <f8000000 8000>;
+ };
+
+ i) Freescale QUICC Engine module (QE)
+ This represents qe module that is installed on PowerQUICC II Pro.
+ Hopefully it will merge backward compatibility with CPM/CPM2.
+ Basically, it is a bus of devices, that could act more or less
+ as a complete entity (UCC, USB etc ). All of them should be siblings on
+ the "root" qe node, using the common properties from there.
+ The description below applies to the the qe of MPC8360 and
+ more nodes and properties would be extended in the future.
+
+ i) Root QE device
+
+ Required properties:
+ - device_type : should be "qe";
+ - model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
+ - reg : offset and length of the device registers.
+ - bus-frequency : the clock frequency for QUICC Engine.
+
+ Recommended properties
+ - brg-frequency : the internal clock source frequency for baud-rate
+ generators in Hz.
+
+ Example:
+ qe@e0100000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ device_type = "qe";
+ model = "QE";
+ ranges = <0 e0100000 00100000>;

+ - reg : Offset and length of the register set for the device
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+ Example:
+ spi@4c0 {
+ device_type = "spi";
+ compatible = "fsl_spi";
+ reg = <4c0 40>;
+ interrupts = <82 0>;
+ interrupt-parent = <700>;

+
+ iii) USB (Universal Serial Bus Controller)
+
+ Required properties:
+ - device_type : should be "usb".
+ - compatible : could be "qe_udc" or "fhci-hcd".
+ - mode : the could be "host" or "slave".
+ - reg : Offset and length of the register set for the device
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+ Example(slave):
+ usb@6c0 {
+ device_type = "usb";
+ compatible = "qe_udc";
+ reg = <6c0 40>;
+ interrupts = <8b 0>;
+ interrupt-parent = <700>;
+ mode = "slave";
+ };
+
+
+ iv) UCC (Unified Communications Controllers)
+
+ Required properties:
+ - device_type : should be "network", "hldc", "uart", "transparent"
+ "bisync" or "atm".
+ - compatible : could be "ucc_geth" or "fsl_atm" and so on.
+ - model : should be "UCC".
+ - device-id : the ucc number(1-8), corresponding to UCCx in UM.
+ - reg : Offset and length of the register set for the device
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+ - pio-handle : The phandle for the Parallel I/O port configuration.
+ - rx-clock : represents the UCC receive clock source.
+ 0x00 : clock source is disabled;
+ 0x1~0x10 : clock source is BRG1~BRG16 respectively;
+ 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+ - tx-clock: represents the UCC transmit clock source;

+
+ Required properties for network device_type:
+ - mac-address : list of bytes representing the ethernet address.
+ - phy-handle : The phandle for the PHY connected to this controller.
+
+ Example:
+ ucc@2000 {
+ device_type = "network";
+ compatible = "ucc_geth";
+ model = "UCC";
+ device-id = <1>;
+ reg = <2000 200>;

+ phy-handle = <212000>;
+ pio-handle = <140001>;
+ };
+
+
+ v) Parallel I/O Ports
+
+ This node configures Parallel I/O ports for CPUs with QE support.
+ The node should reside in the "soc" node of the tree. For each
+ device that using parallel I/O ports, a child node should be created.
+ See the definition of the Pin configuration nodes below for more
+ information.
+
+ Required properties:
+ - device_type : should be "par_io".
+ - reg : offset to the register set and its length.
+ - num-ports : number of Parallel I/O ports
+
+ Example:
+ par_io@1400 {
+ reg = <1400 100>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ device_type = "par_io";
+ num-ports = <7>;
+ ucc_pin@01 {
+ ......
+ };
+
+
+ vi) Pin configuration nodes
+
+ Required properties:
+ - linux,phandle : phandle of this node; likely referenced by a QE
+ device.
+ - pio-map : array of pin configurations. Each pin is defined by 6
+ integers. The six numbers are respectively: port, pin, dir,
+ open_drain, assignment, has_irq.
+ - port : port number of the pin; 0-6 represent port A-G in UM.
+ - pin : pin number in the port.
+ - dir : direction of the pin, should encode as follows:
+
+ 0 = The pin is disabled
+ 1 = The pin is an output
+ 2 = The pin is an input
+ 3 = The pin is I/O
+
+ - open_drain : indicates the pin is normal or wired-OR:
+
+ 0 = The pin is actively driven as an output
+ 1 = The pin is an open-drain driver. As an output, the pin is
+ driven active-low, otherwise it is three-stated.
+
+ - assignment : function number of the pin according to the Pin Assignment
+ tables in User Manual. Each pin can have up to 4 possible functions in
+ QE and two options for CPM.
+ - has_irq : indicates if the pin is used as source of exteral
+ interrupts.
+
+ Example:
+ ucc_pin@01 {
+ linux,phandle = <140001>;
+ pio-map = <
+ /* port pin dir open_drain assignment has_irq */

+ - mode : the could be "host" or "slave".
+ - ranges : Should be defined as specified in 1) to describe the
+ translation of MURAM addresses.
+ - data-only : sub-node which defines the address area under MURAM
+ bus that can be allocated as data/parameter
+
+ Example:
+
+ muram@10000 {
+ device_type = "muram";
+ ranges = <0 00010000 0000c000>;
+
+ data-only@0{
+ reg = <0 c000>;
+ };
+ };
More devices will be defined as this spec matures.

All those drivers are bogus and need to be updated. They should be
marked CONFIG_BROKEN

Hello:
For the automated cross-compile builds at OSDL, powerpc 64-bit
'allmodconfig' is failing. The warnings/errors below appear in
the 'modpost' stage of kernel compiles for 2.6.18 and -mm2 kernels.
Thanks;
