      [POWERPC] 4xx: Workaround for CHIP_11 Errata · 13c501e6
      Josh Boyer 提交于
      The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that
      causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction
      requests that cross the end-of-memory-range boundary.  Since the DDR
      controller only returns the valid portion of a read request, the bridge
      will prevent other PLB masters from completing their transactions.
      
      This implements the recommended workaround for this errata for chips that
      use older versions of firmware that do not already handle it.  The last
      4KiB of memory are hidden from the kernel to prevent the problem
      transactions from occurring.

      fbdev: powerpc: driver for Freescale 8610 and 5121 DIU · 9b53a9e2
      York Sun 提交于
      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.
