* [POWERPC] 8xx: mpc885ads pcmcia supportVitaly Bordug2007-07-102-2/+22
| | | | | | | | | | | | | | | | | | | | Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as of_device, so only arch/powerpc stuff is capable to use it, which now implies only mpc885ads reference board. To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.

* [POWERPC] 86xx: Workaround PCI_PRIMARY_BUS usageKumar Gala2007-06-291-0/+6
| | | | | | | | | | | | | | | The Freescale PCI-e controllers have an issue in that they use the PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which bus number to match on when generating a type 0 config cycle. The issue is if we are renumbering bus numbers to match Linux we will try setting the PCI_PRIMARY_BUS and will not know which bus number to use for generating type 0 config cycles. We surpress writing the register in the P2P bridge and always keep it at zero. In the future when proper PCI domain support is working we should be able to remove this.

* [POWERPC] Added indirect_type to handle variants of PCI opsKumar Gala2007-06-291-6/+16
| | | | | | | | | | | | The generic PCI config ops indirect support for ppc32 covers only two cases (implicit vs explicit) type 0/1 config cycles via set_cfg_type. Added a indirect_type bit mask to handle other variants. Added support for PCI-e extended registers and moved the cfg_type handling into the bit mask for ARCH=powerpc. We can also use this to handle indirect quirks. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | Removed the remants of bus_offset and use self_busno in the mv64x60 case and use pci_assign_all_buses on 83xx/85xx. 83xx/85xx have multiple PHBs and the firmwares on these devices tend not to handle topologies with P2P bridges well so we let Linux just reassign the bus numbers to match.

| | | | | | | | | Added self_busno to pci_controller and indirect PCI ops to be set by board code to indicate which bus number to use when talking to the PHB.

* [POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala2007-06-292-2/+0
| | | | | | | | | | | The Freescale and Marvell PCI controllers dont require explicit setting for type 1 config cycles. They handle producing them by implicitly looking at the bus, devfn. The TSI108 and 52xx don't use the generic PCI indirect code and thus don't bother with set_cfg_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] Don't link timer.o for powerpc systems using generic rtcGuennadi Liakhovetski2007-06-251-0/+2
| | | | | | | | | | | | | | | | | With both generic rtc and powerpc timer suspend / resume code now in the (powerpc.git) tree, powerpc platforms using the generic timer and enabling power management will have timer.o linked in the kernel, which they don't need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save zero-time and return no error on suspend... As a possible solution we can choose not to build timer.o when RTC_CLASS is enabled. However, I can imagine systems with 2 rtc's, one served by the ppc-rtc, another one generic built as a module, in which case using the ppc-rtc for suspend / resume will be impossible. Not to say, that such a configuration would be ugly... Signed-off-by: G. Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Fix problems with device tree representation of TSI-1xx bridgesDavid Gibson2007-06-141-11/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes some problems with the way the some things represented in the device tree for the Holly and Taiga boards. This means changes both to the dts files, and to the code which instantiates the tsi108 ethernet platform devices based on the device tree. - First, and most importantly, the ethernet PHYs are given with an identical 'reg' property. This reg currently encodes the accessible register used to initiate mdio interaction with the PHYs, rather than a meaningful address on the parent bus (mdio in this case), which is incorrect. Instead we give the address of these registers as 'reg' in the mdio node itself, and encode the ID of each phy in their 'reg' propertyies. - Currently the platform device constructor enables a workaround in the tsi108 ethernet driver based on the compatible property of the PHY. This is incorrect, because the workaround in question is necessary due to the board's wiring of the PHY, not the model of PHY itself. This patch alters the constructor to instead enable the workaround based on a new special property in the PHY node. - The compatible properties on a number of nodes in the device tree are insufficiently precise. In particular the PHYs give only "bcm54xx", which is broken, since there are many bcm54xx PHY models, and they have differences which matter. The mdio had a compatible property of "tsi-ethernet" identical to the ethernet MAC nodes, which doesn't make sense. The ethernet, i2c, bridge and PCI nodes were given only as "tsi-*" which is somewhat inprecise, we replace with "tsi108-*" in the case of Taiga (which has a TSI108 bridge), and "tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109 bridge). - We remove some "model" properties from the ethernets on Taiga board which were neither useful nor adequately precise. - On Holly we change to using a dtc label instead of a full path to reference the MPIC node, which makes the dts a little more readable.

* [POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi2007-05-095-41/+41
| | | | | | | | | | | | | | | | | | | | The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

| | | | | | | | | | | | | | powerpc_flash_init() implements a broken way of probing for flash devices supported by the physmap_of driver. It finds all nodes in the device tree with device_type=="rom" and instantiates of_platform devices for them. This is fundamentally incompatible with the normal and correct way of probing for of_platform_bus_probe(). Platforms which relied on powerpc_flash_init()s behaviour (none are in-tree) will have to update their platform probing code to correctly probe busses containing flash devices.

| | | | | | | | | | | | | | | | MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me. This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5. If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.

| * | [POWERPC] QE: automatically select QE optionsTimur Tabi2007-03-261-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the Kconfig files so that the Freescale QE options are automatically selected if a QE device is selected. Previously, you'd need to manually select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet. Now, the QE Gigabit Ethernet option is always available if the device has a QE, and UCC_FAST is automatically enabled. A side-effect is that the "QE Options" menu no longer exists.

| * | [POWERPC] 86xx/85xx: Move 8641 PCI-Express to arch/powerpc/sysdev/fsl_pcie.c.Jon Loeliger2007-03-262-0/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This move sets the stage for the use of generic PCI Express code in 85xx and 86xx parts from FSL. Subsequent patches for 8548 and 8544 will be able to use this shared code.

| * | [POWERPC] Generic time suspend/resume codeJohannes Berg2007-03-262-0/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the time suspend/restore code that was done through a PMU notifier in arch/platforms/powermac/time.c. Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys device and handles time of day suspend/resume through that. This should probably be replaced by using the generic RTC framework but for now it gets rid of the arcane powermac specific hack.
