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
