2009-03-27powerpc/85xx: Add support for the "socrates" board (MPC8544).Wolfgang Grandegger
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>; }; Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Ilya Yanok <yanok@emcraft.com> Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Dmitry Rakhchev <rda@emcraft.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-03-24powerpc/85xx: Move gianfar mdio nodes under the ethernet nodesAnton Vorontsov
Currently it doesn't matter where the mdio nodes are placed, but with power management support (i.e. when sleep = <> properties will take effect), mdio nodes placement will become important: mdio controller is a part of the ethernet block, so the mdio nodes should be placed correctly. Otherwise we may wrongly assume that MDIO controllers are available during sleep.

2008-12-30powerpc/85xx: Add local_irq_restore in error handling codeJulia Lawall
There is a call to local_irq_restore in the normal exit case, so it would seem that there should be one on an error return as well. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; expression E,E1,E2; @@ local_irq_save(l); ... when != local_irq_restore(l) when != spin_unlock_irqrestore(E,l) when any when strict ( if (...) { ... when != local_irq_restore(l) when != spin_unlock_irqrestore(E1,l) + local_irq_restore(l); return ...; } | if (...) + {local_irq_restore(l); return ...; + } | spin_unlock_irqrestore(E2,l); | local_irq_restore(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-10-31powerpc/mpic: Fix regression caused by change of default IRQ affinityKumar Gala
The Freescale implementation of MPIC only allows a single CPU destination for non-IPI interrupts. We add a flag to the mpic_init to distinquish these variants of MPIC. We pull in the irq_choose_cpu from sparc64 to select a single CPU as the destination of the interrupt. This is to deal with the fact that the default smp affinity was changed by commit 18404756765c713a0be4eb1082920c04822ce588 ("genirq: Expose default irq affinity mask (take 3)") to be all CPUs.

2008-10-22powerpc: Move memory size print into common show_cpuinfo for 32-bitBecky Bruce
Most of the platforms were printing the size of the memory in their show_cpuinfo implementations. This moves that to the common show_cpuinfo, so that all 32-bit platforms will now print the size of memory. I also update the code to deal with the fact that total_memory is now a phys_addr_t.

2008-10-13powerpc: make Freescale QE support a selectable Kconfig optionTimur Tabi
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>

2008-07-16powerpc/85xx/86xx: some refactoring for fsl_uli1575 codeAnton Vorontsov
- Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks.

2008-07-16powerpc: pci config cleanupJohn Rigby
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.

2008-06-09[POWERPC] 85xx: MPC85xx MDS - Unconditionally select PHYLIB for board fixupsKumar Gala
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>
