* net: fec_mxc: change fec_mii_setspeed parameterTroy Kisky2013-01-28-5/+5
| | | | | | | | | | | | | Only the hardware ethernet registers are needed for this function, so don't pass the more general structure. I'm trying to separate MII and fec. This also fixes MX28 fec_mii_setspeed use on secondary ethernet port This was found by inspection of the code and should be checked on real hardware.

* FEC: Rework the TX wait mechanismMarek Vasut2012-09-27-9/+11
| | | | | | | | | | | | | | | | | | | | | | | The mechanism waiting for transmission to finish in fec_send() now relies on the E-bit being cleared in the TX buffer descriptor. In case of data cache being on, this means invalidation of data cache above this TX buffer descriptor on each test for the E-bit being cleared. Apparently, there is another way to check if the transmission did complete. This is by checking the TDAR bit in the X_DES_ACTIVE register. Reading a register does not need any data cache invalidation, which is beneficial. Rework the sequence that wait for completion of the transmission so that the TDAR bit is tested first and afterwards check the E-bit being clear. This cuts down the number of cache invalidation calls to one.

* FEC: Do not pass unaligned buffer to network stackMarek Vasut2012-09-27-1/+2
| | | | | | | | | | | | | | Do not pass unaligned RX buffer to the upper layers. The upper layer, especially in the ARP case, recycles the buffer and passes it back into the FEC, into it's TX path. With caches enabled, the FEC hangs on this from time to time.

* net: fec_mxc: Fix setting of RCR for xMIIbenoit.thebaudeau@advans2012-07-19-5/+3
| | | | | | | | | | | | | | | | | | At least on i.MX25, the RMII mode did not work, which is fixed by this patch. The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set it accordingly. According to the xMII and 7-wire (aka GPSI) standards, full duplex should be available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may support full duplex for 7-wire too, but the reference manual does not say that, so avoid an invalid assumption. Actually, the choice between half and full duplex also depends on the endpoint/switch/repeater configuration, so a config option could be added for that, but there has been no need for it so far.

* net: fec_mxc: add PHYLIB supportTroy Kisky2012-02-27-48/+96
| | | | | | | | | | | | | | | | | | | | | Surround non PHYLIB routines miiphy_restart_aneg and miiphy_wait_aneg with ifndef CONFIG_PHYLIB. When later PHYLIB is required it is easy to delete the non-PHYLIB code. This separation idea came from Andy Fleming. fec_miiphy_read, and fec_miiphy_write changed to fec_phy_read, and fec_phy_write with argument changes. Deprecated miiphy_register is no longer used. Both old and new PHYLIB code now use mdio_register. Cleanup some debug prints. Inline function fec_miiphy_fec_to_eth is no longer necessary. Moved to the single call location.

* FEC: Allow multiple FECesMarek Vasut2011-09-30-30/+49
| | | | | | | | | | | | | | | | | | | This patch allows user to register multiple FEC controllers. To preserve compatibility with older boards, the mxcfec_register() call is still in place. To use multiple controllers, new macro is in place, the mxcfec_register_multi(), which takes more arguments. The syntax is: mxcfec_register_multi(bd, FEC ID, FEC PHY ID on the MII bus, base address); To disable the fecmxc_register() compatibility stuff, define the macro CONFIG_FEC_MXC_MULTI. This will remove the requirement for defining IMX_FEC_BASE and CONFIG_FEC_MXC_PHYADDR.
