[Qemu-devel] [PATCH v3 0/2] 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.

The main change in this version is the use of a single rx fifo instead
of multiple per-packet fifos. I added functions to manipulate the rx
fifo and, for consistency, also functions to manipulate tx fifo.

Another difference from v2 is that the function can_receive() now
can't really know if the next packet can be stored in the fifo because
with a single fifo this depends on the size of packet. So the
functions only checks if rx is enabled; if the packet can't be stored
it will be dropped in receive().

Changelog:
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
