* powerpc/85xx: Introduce support for the Freescale P1022DS reference boardTimur Tabi2010-08-04
| | | | | | | | | | | | | | Introduce basic support for the Freescale P1022DS reference board, based on the Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.

* powerpc: make Freescale QE support a selectable Kconfig optionTimur Tabi2008-10-13
| | | | | | | | | | | | Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable option, thereby allowing users to compile kernels without any QE support. The drawback is that QE support is now disabled by default on platforms that have a QE, and so a defconfig is needed to enable QE and QE devices (like UCC GETH). Fortunately, all the current relevant defconfigs do that already. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc: pci config cleanupJohn Rigby2008-07-16
| | | | | | | | | | | | | | | | | | | | Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

| * [POWERPC] 85xx: MPC85xx MDS - Unconditionally select PHYLIB for board fixupsKumar Gala2008-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC85xx MDS board requires some board level tweaks of the PHYs that either the eTSEC (gianfar) or UCC ethernet controllers are connected to. Its possible to build the phylib as a module, however this breaks the board level fix ups because phy_read and phy_write are not available if we build as a module. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in MPC85xx MDS support. This was determined to be the easiest soultion even though it prevents the user from removing PHYLIB support if they decide they don't want it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala2007-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] 85xxCDS: Allow 8259 cascade to share an MPIC interrupt line.Randy Vinson2007-07-23
| | | | | | | | | | | | | | | | | | | | 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.

* powerpc: Merge enough to start building in arch/powerpc.Paul Mackerras2005-09-26
This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
