      powerpc/booke: Add support for new e500mc core · 3dfa8773
      Kumar Gala 提交于
      The new e500mc core from Freescale is based on the e500v2 but with the
      following changes:
      
      * Supports only the Enhanced Debug Architecture (DSRR0/1, etc)
      * Floating Point
      * No SPE
      * Supports lwsync
      * Doorbell Exceptions
      * Hypervisor
      * Cache line size is now 64-bytes (e500v1/v2 have a 32-byte cache line)

      powerpc/4xx: Workaround for PPC440EPx/GRx PCI_28 Errata · 5ce4b596
      Josh Boyer 提交于
      The 440EPx/GRx chips don't support PCI MRM commands.  Drivers determine this
      by looking for a zero value in the PCI cache line size register.  However,
      some drivers write to this register upon initialization.  This can cause
      MRMs to be used on these chips, which may cause deadlocks on PLB4.
      
      The workaround implemented here introduces a new indirect_type flag, called
      PPC_INDIRECT_TYPE_BROKEN_MRM.  This is set in the pci_controller structure in
      the pci fixup function for 4xx PCI bridges by determining if the bridge is
      compatible with 440EPx/GRx.  The flag is checked in the indirect_write_config
      function, and forces any writes to the PCI_CACHE_LINE_SIZE register to be
      zero, which will disable MRMs for these chips.
      
      A similar workaround has been tested by AMCC on various PCI cards, such as
      the Silicon Image ATA card and Intel E1000 GIGE card.  Hangs were seen with
      the Silicon Image card, and MRMs were seen on the bus with a PCI analyzer.
      With the workaround in place, the card functioned properly and only Memory
      Reads were seen on the bus with the analyzer.
