2007-10-11[POWERPC] 85xx: Killed <asm/mpc85xx.h>Kumar Gala7-142/+9
asm-powerpc/mpc85xx.h was really a hold over from arch/ppc. Now that more decoupling has occurred we can remove <asm/mpc85xx.h> and some of its legacy. As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h for 85xx platforms. This is a stop gap until drivers stop using CPM_MAP_ADDR. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-10-08[POWERPC] 85xx: mpc85xx_mds - reset UCC ethernet properlyAnton Vorontsov1-12/+16
Apart from that the current code doesn't compile it's also meaningless with regard to the MPC8568E-MDS' BCSR. This patch used to reset UCCs properly. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-08[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascadingAnton Vorontsov1-1/+1
set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.

2007-10-08[POWERPC] 85xx/86xx: refactor RSTCR reset codeKumar Gala7-84/+6
On the majority of 85xx & 86xx we have a register that's ability to assert HRESET_REQ to reset the board. We refactored that code so it can be shared between both platforms into fsl_soc.c and removed all the duplication in each platform directory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-08[POWERPC] Use for_each_ matching routinues for pci PHBsKumar Gala4-18/+35
On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Renamed functions in 85xx_ds from 8544 to 85xx. Kept an unique machine def/probe for the MPC8544 DS board to handle some subtle differences between the future board based on the DS platform.

Remove includes of files that existed in arch/ppc that we dont need in arch/powerpc anymore. The following includes were removed: <asm/amigappc.h> <asm/bootinfo.h> <asm/ppcboot.h> <asm/ppc_sys.h> <asm/residual.h> <asm/m8260_pci.h> This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be needed and thus removed.

2007-08-17[POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala2-199/+16
The interrupt routing in the device trees for the ULI M1575 was inproperly using the interrupt line field as pci function. Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

2007-08-10[POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms ↵Kim Phillips1-1/+0
with QE UEC" This reverts commit 3baee955953957be5496cd28e9c544d9db214262. That commit was a mistake from the start; I added mdio type to the bus scan list early on in my ucc_geth migrate to phylib development, which is just pure wrong (the ucc_geth_mii driver creates the mii bus and the PHY layer handles PHY enumeration without translation). This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb: Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()" which was basically trying to hide a symptom of the original mistake this revert fixes.

2007-07-24[POWERPC] 85xxCDS: Delay 8259 cascade hookup.Randy Vinson1-11/+25
The interrupts of an E100 card inserted in PCI slot 4 may be on at bootup. The resulting interrupt flood interacts with the 8259 cascade handler and prevents proper boot up. There is a quirk for the E100 that will disable the E100's interrupts but to use it, the 8259 cascade hookup must be delayed until after the quirk has run. This patch delays the 8259 cascade hookup by registering a device_initcall() which runs after the PCI quirk for the E100.

2007-07-23[POWERPC] 85xxCDS: Make sure restart resets the PCI bus.Randy Vinson1-0/+35
The current 85xxCDS restart code fails to reset the PCI bus which can lead to odd behavior after the restart. This patch uses the VIA Super Southbridge to perform a PCI reset which will reset the entire system. NOTE: Since the VIA chip is behind a PCI-to-PCI bridge which can be disabled with a switch setting, it may not be possible to perform the PCI bus reset. In this case, the code defaults to the previous restart mechanism. Signed-off-by: Randy Vinson <rvinson@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-07-23[POWERPC] 85xxCDS: Allow 8259 cascade to share an MPIC interrupt line.Randy Vinson2-6/+32
The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy 8259 interrupt controller pair contained within a VIA VT82C686B Southbridge on the main carrier board. The processor complex plugs into the carrier card using a PCI slot which limits the available interrupts to the INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed through a gate array and connected to the PCI INTA interrupt line. The normal interrupt chaining hook (set_irq_chained_handler) does not allow sharing of the chained interrupt which prevents the use of PCI INTA by PCI devices. This patch allows the 8259 cascade pair to share their interrupt line with PCI devices. NOTE: The addition of the .end routine for the MPIC is not strictly necessary for this patch. It's there so this code will run from within the threaded interrupt context used by the Real Time patch.

2007-07-23[POWERPC] Fixup resources on pci_bus for PCIe PHB when no device is connectedKumar Gala1-0/+1
On the 85xx/86xx PCIe controllers if there is no device connected to the PHB we will still allocate a pci_bus for downstream bus of the virtual P2P bridge. However the resources allocated to the downstream bus are not correct and so we just mimic the resources from the upstream pci_bus. 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.

2007-06-29[POWERPC] Remove hack to determine the 2nd PHBs bus numberKumar Gala2-9/+1

2007-06-29[POWERPC] Pass the pci_controller into pci_exclude_deviceKumar Gala2-2/+4
There are times that we need to know which controller we are on to decide how to exclude devices properly.

2007-06-29[POWERPC] Remove set_cfg_type for PCI indirect users that don't need itKumar Gala1-1/+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>
