    Various improvements for configuring the MPC5200 MII link from the
    device tree:
    * Look for 'current-speed' property for fixed speed MII links
    * Look for 'fsl,7-wire-mode' property for boards using the 7 wire mode
    * move definition of private data structure out of the header file

  • 9b53a9e28   fbdev: powerpc: driver for Freescale 8610 and 5121 DIU ... Browse Code »

    The following features are supported:
    plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
    plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
    plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
    Special ioctls support AOIs

    All /dev/fb* can be used as regular frame buffer devices, except hardware
    change can only be made through /dev/fb0. Changing pixel clock has no effect
    on other fbs.

    Limitation of usage of AOIs:
    AOIs on the same plane can not be horizonally overlapped
    AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
    AOIs can not beyond phisical display area. Application should check AOI geometry
    before changing physical resolution on /dev/fb0

    required command line parameters to preallocate memory for frame buffer diufb.

    optional command line parameters to set modes and monitor
    video=fslfb:[resolution][,bpp][,monitor]
    Syntax:

    Resolution
    xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
    eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60

    Bpp
    bpp=32, bpp=24, or bpp=16

    Monitor
    monitor=0, monitor=1, monitor=2
    0 is DVI
    1 is Single link LVDS
    2 is Double link LVDS

    Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
    monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
    monirot port for MPC5121ADS has no effect.

    If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

  • ecc6cd73b   [POWERPC] Start removing linux,network-index in favour of aliases ... Browse Code »

    This patch alters the bootwrapper for a number of machines (roubhly
    all 4xx based cuboot or treeboot platforms) to use aliases instead of
    the linux,network-index hack to work out which MAC address to attach
    to which ethernet device node.

    The now obsolete linux,network-index properties are removed from the
    corresponding device trees. This won't break backwards compatiblity,
    because in cases where this fixup code is relevant, the device tree is
    part of the kernel image.

    The references to linux,network-index are removed from
    booting-without-of.txt. Not only is it now deprecated, but as a hack
    applicable only when the device tree blob and fixup code were in the
    same image, this property never belonged in booting-without-of.txt
    which describes the interface between the kernel and firmware or
    bootloaders which produce a device tree. By the time the device tree
    reaches the kernel, all the MAC addresses must be fully filled in.

  • ab99eee8a   [POWERPC] Xilinx: Update booting-without-of. ... Browse Code »

    This now better describes what the UBoot device tree generator
    actually does. In particular:

    1) Nodes have a label derived from the device name, and a node name
    derived from a generic version of the device type, e.g. 'ethernet',
    'serial', etc.

    2) Usage of compound nodes (representing more than one device in the
    same IP) which actually works. This requires having a valid
    compatible node, and all the other things that a bus normally has.
    I've chosen 'xlnx,compound' as the bus name to describe these compound
    nodes.

    In addition, I've clarified some of the language relating to how mhs
    nodes should be represent in the device tree.

  • 20474abda   [POWERPC] Fix cache line vs. block size confusion ... Browse Code »

    We had an historical confusion in the kernel between cache line
    and cache block size. The former is an implementation detail of
    the L1 cache which can be useful for performance optimisations,
    the later is the actual size on which the cache control
    instructions operate, which can be different.

    For some reason, we had a weird hack reading the right property
    on powermac and the wrong one on any other 64 bits (32 bits is
    unaffected as it only uses the cputable for cache block size
    infos at this stage).

    This fixes the booting-without-of.txt documentation to mention
    the right properties, and fixes the 64 bits initialization code
    to look for the block size first, with a fallback to the line
    size if the property is missing.

  • 1d3bb9964   Device tree aware EMAC driver ... Browse Code »

    Based on BenH's earlier work, this is a new version of the EMAC driver
    for the built-in ethernet found on PowerPC 4xx embedded CPUs. The
    same ASIC is also found in the Axon bridge chip. This new version is
    designed to work in the arch/powerpc tree, using the device tree to
    probe the device, rather than the old and ugly arch/ppc OCP layer.

    This driver is designed to sit alongside the old driver (that lies in
    drivers/net/ibm_emac and this one in drivers/net/ibm_newemac). The
    old driver is left in place to support arch/ppc until arch/ppc itself
    reaches its final demise (not too long now, with luck).

    This driver still has a number of things that could do with cleaning
    up, but I think they can be fixed up after merging. Specifically:
    - Should be adjusted to properly use the dma mapping API.
    Axon needs this.
    - Probe logic needs reworking, in conjuction with the general
    probing code for of_platform devices. The dependencies here between
    EMAC, MAL, ZMII etc. make this complicated. At present, it usually
    works, because we initialize and register the sub-drivers before the
    EMAC driver itself, and (being in driver code) runs after the devices
    themselves have been instantiated from the device tree.

  • 15f8c604a   [POWERPC] cpm: Describe multi-user ram in its own device node. ... Browse Code »

    The way the current CPM binding describes available multi-user (a.k.a.
    dual-ported) RAM doesn't work well when there are multiple free regions,
    and it doesn't work at all if the region doesn't begin at the start of
    the muram area (as the hardware needs to be programmed with offsets into
    this area). The latter situation can happen with SMC UARTs on CPM2, as its
    parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
    support moving it.

    It is now described with a muram node, similar to QE. The current CPM
    binding is sufficiently recent (i.e. never appeared in an official release)
    that compatibility with existing device trees is not an issue.

    The code supporting the new binding is shared between cpm1 and cpm2, rather
    than remain separated. QE should be able to use this code as well, once
    minor fixes are made to its device trees.

  • 96fca1dea   [POWERPC] Document local bus nodes in the device tree, and update cuboot-pq2. ... Browse Code »

    The localbus node is used to describe devices that are connected via a chip
    select or similar mechanism. The advantages over placing the devices under
    the root node are that it can be probed without probing other random things
    under the root, and that the description of which chip select a given device
    uses can be used to set up mappings if the firmware failed to do so in a
    useful manner.

    cuboot-pq2 is updated to match the binding; previously, it called itself
    chipselect rather than localbus, and used phandle linkage between the
    actual bus node and the control node (the current agreement is to simply use
    the fully-qualified address of the control registers, and ignore the overlap
    with the IMMR node).
