[Qemu-devel] [PATCH v4 0/3] hw/arm: add ethernet support to Allwinner A10

[Beniamino Galvani]

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

Changelog:
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
