[Qemu-devel] [PATCH v5 0/4] hw/arm: add ethernet support to Allwinner A10

[Beniamino Galvani <b.galvani@gmail.com>]

This patch series adds support for the EMAC Fast Ethernet controller
found on Allwinner SoCs to the Allwinner A10.

Changelog:
v5: Address comments from Peter Crosthwaite and Peter Maydell:
    * Move reinitialization of fifo head to a new patch
    * Remove fifo8_has_space() and add fifo8_num_free(),fifo8_num_used()
    * Improve documentation of new fifo8 functions
    * Add restriction on fifo8_pop_buf() 'max' argument as originally
      suggested by Peter C.: it must not be greater than the number of
      bytes in the fifo
    * Change license of EMAC model to GPLv2 
    * Check if tx length register is greater than data in fifo

v4: Address comments from Peter Crosthwaite and Andreas Färber:
    * Add functions for multiple bytes push/pop to Fifo8
    * Get rid of custom fifo implementation and use generic one for
      both tx and rx
    * Rename aw_emac_mdio_read -> RTL8201CP_mdio_read
    * Allow reception of new packets from net layer only when there is
      space for a full size frame
    * Change TYPE_AW_EMAC from "allwinner_emac" to "allwinner-emac"
    * Property "phyaddr" -> "phy-addr"
    * Remove trailing newlines from error_report() messages

v3: Address comments from Peter Crosthwaite and Stefan Hajnoczi:
    * Use a single, big rx fifo instead of per-packet fifo
    * Remove link_ok field from PHY state
    * Call set_link() on post_load
    * Add missing PHY registers
    * Implement reset() method
    * Rename AwEmacMii -> RTL8201CPState
    * Rename mii_{read,write} -> aw_emac_mdio_{read,write}

v2: Address Peter Crosthwaite's comments:
    * Make phy address customizable through a property
    * Call qemu_flush_queued_packets() when rx becomes possible
    * Always create EMAC instance in SoC
    * Use uint8 arrays for fifos
    * Minor cleanups

Beniamino Galvani (4):
  util/fifo8: implement push/pop of multiple bytes
  util/fifo8: clear fifo head upon reset
  hw/net: add support for Allwinner EMAC Fast Ethernet controller
  hw/arm/allwinner-a10: initialize EMAC
