2016-07-12Clean up header guards that don't match their file nameMarkus Armbruster
Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

2016-06-02Add ENET/Gbps Ethernet support to FEC deviceJean-Christophe Dubois
The ENET device (present in i.MX6) is "derived" from FEC and backward compatible with it. This patch adds the necessary support of the added feature in the ENET device to allow Linux to use it (on supported processors).

2015-09-07i.MX: Add FEC Ethernet EmulatorJean-Christophe Dubois
This is based on mcf_fec.c FEC implementation for Coldfire * A generic PHY was added (borrowwed from LAN9118) * The buffer management is also modified as buffers are slightly different between Coldfire and i.MX Signed-off-by: Jean-Christophe Dubois <jcd@tribudubois.net> Reviewed-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Message-id: fb314f8a120aa49f8f6ad886f312c649b484fb5a.1441057361.git.jcd@tribudubois.net Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-27hw/net: add simple phy support to mcf_fec driverGreg Ungerer
The Linux fec driver needs at least basic phy support to probe and work. The current qemu mcf_fec emulation has no support for the reading or writing of the MDIO lines to access an attached phy. This code adds a very simple set of register results for a fixed phy setup - very similar to that used on an m5208evb board. This is enough to probe and identify an emulated attached phy.

2015-07-27hw/net: add ANLPAR bit definitions to generic miiGreg Ungerer
Add a base set of bit definitions for the standard MII phy "Auto-Negotiation Link Partner Ability Register" (ANLPAR). The original definitions moved into mii.h from the allwinner_emac driver did not define these.

2015-07-27hw/net: create common collection of MII definitionsGreg Ungerer
Create a common set of definitions of address and register values for ethernet MII phys. A few of the current ethernet drivers have at least a partial set of these definitions. Others just use hard coded raw constant numbers. This initial set is copied directly from the allwinner_emac code.

2014-02-08hw/net: add support for Allwinner EMAC Fast Ethernet controllerBeniamino Galvani
This patch adds support for the Fast Ethernet MAC found on Allwinner SoCs, together with a basic emulation of Realtek RTL8201CP PHY. Since there is no public documentation of the Allwinner controller, the implementation is based on Linux kernel driver.
