2016-09-25powerpc: Convert fsl_rstcr_restart to a reset handlerAndrey Smirnov
Convert fsl_rstcr_restart into a function to be registered with register_reset_handler(). Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> [scottwood: Converted mvme7100 as well] Signed-off-by: Scott Wood <oss@buserror.net>
2016-07-21powerpc: Move 32-bit probe() machine to later in the boot processBenjamin Herrenschmidt
This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.

2012-09-12powerpc/fsl-pci: Unify pci/pcie initialization codeJia Hongtao
We unified the Freescale pci/pcie initialization by changing the fsl_pci to a platform driver. In previous PCI code architecture the initialization routine is called at board_setup_arch stage. Now the initialization is done in probe function which is architectural better. Also It's convenient for adding PM support for PCI controller in later patch. Now we registered pci controllers as platform devices. So we combine two initialization code as one platform driver.

2012-02-23powerpc/mpic: Remove duplicate MPIC_WANTS_RESET flagKyle Moffett
There are two separate flags controlling whether or not the MPIC is reset during initialization, which is completely unnecessary, and only one of them can be specified in the device tree. Also, most platforms in-tree right now do actually want to reset the MPIC during initialization anyways, which means lots of duplicate code passing the MPIC_WANTS_RESET flag. Fix all of the callers which currently do not pass the MPIC_WANTS_RESET flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET flag and make the code reset the MPIC by default.

2011-12-07powerpc/mpic: Invert the meaning of MPIC_PRIMARYKyle Moffett
It turns out that there are only 2 in-tree platforms which use MPICs which are not "primary": IBM Cell and PowerMac. To reduce the complexity of the typical board setup code, invert the MPIC_PRIMARY bit into MPIC_SECONDARY.

2011-12-07powerpc/mpic: Search for open-pic device-tree node if NULLKyle Moffett
Almost all PowerPC platforms use a standard "open-pic" device node so the mpic_alloc() function now accepts NULL for the device-node. This will cause it to perform a default search with of_find_matching_node(). Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-12-07powerpc: Consolidate mpic_alloc() OF address translationKyle Moffett
Instead of using the open-coded "reg" property lookup and address translation in mpic_alloc(), directly call of_address_to_resource(). This includes various workarounds for special cases which the naive of_address_translate() does not. Afterwards it is possible to remove the copiously copy-pasted calls to of_address_translate() from the 85xx/86xx/powermac platforms.

2011-11-24powerpc/85xx: consolidate of_platform_bus_probe callsDmitry Eremin-Solenikov
85xx board files have a lot of duplication in *_publish_devices()/ *_declare_of_platform_devices() functions. Merge that into a single function common to most of the boards. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-06-23powerpc/85xx: Stop using ppc_md.init on socratesKumar Gala
Match what other 85xx platforms do for of_platform_bus_probe and use machine_device_initcall. This is one small step in killing of ppc_md.init. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
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>
