* net,fec: Shorten device name as done for other driversStefano Babic2010-08-09-1/+1
| | | | | | | | | | After discussion on the ML it is suggested to drop unrequired and not useful characters from the device name. This patch changes the name for the fec_mxc driver from "FEC_MXC" to "FEC". Signed-off-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* net: fec_mxc: add write_hwaddr supportHeiko Schocher2010-05-03-1/+1
| | | | | | | tested on the magnesium board. Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* fec_mxc.c: Fix MX27 FEC MAC validity checkEric Jarrige2010-05-03-1/+1
| | | | | | | | Fix MX27 FEC logic to check validity of the MAC address in fuse. Only null (empty fuse) or invalid MAC address was retrieved from mx27 fuses before this change. Signed-off-by: Eric Jarrige <jorasse@armadeus.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* fec_mxc don't use internal eeprom on MX25John Rigby2010-05-03-2/+2
| | | | | | | Avoid using the internal eeprom on MX25 like MX51 already does. Signed-off-by: John Rigby <jcrigby@gmail.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* net, fec_mxc: only setup the device enetaddr with eeprom valueHeiko Schocher2010-03-31-1/+0
| | | | | | | | Only fill the device enetaddr with the contents of the eeprom, do not program it in MAC address registers Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Ben Warren <biggerbadderben@gmail.com>
* fec_mxc: add MX25 supportJohn Rigby2010-03-07-1/+30

* fec_mxc: cleanup and factor out MX27 dependenciesJohn Rigby2010-03-07-6/+9
| | | | | | | | | | | | | general cleanup move clock init to cpu_eth_init in cpu/arm926ejs/mx27/generic.c make MX27 specific phy init conditional on CONFIG_MX27 replace call to imx_get_ahbclk with one to imx_get_fecclk and define imx_get_fecclk in include/asm-arm/arch-mx27/clock.h Signed-off-by: John Rigby <jcrigby@gmail.com> CC: Ben Warren <biggerbadderben@gmail.com> CC: Fred Fan <fanyefeng@gmail.com> CC: Tom <Tom.Rix@windriver.com>
* fec_mxc: add support for MX51 processorStefano Babic2010-02-06-41/+32
| | | | | | | | The patch add support for the Freescale mx51 processor to the FEC ethernet driver. Signed-off-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* fec_mxc: incomplete error handlingJohn Ogness2009-12-13-0/+1
| | | | | | | | | | fec_init() will only allocate fec->base_ptr if it is non-NULL. But the cleanup routine on error will free the pointer without setting it to NULL. This means that a later call to fec_init() would result in using an invalid pointer. Signed-off-by: John Ogness <john.ogness@linutronix.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* mxc_fec: avoid free() calls to already freed pointers.javier Martin2009-11-11-5/+7
| | | | | | | | | | | | | | Sometimes, inside NetLoop, eth_halt() is called before eth_init() has been called. This is harmless except for free() calls to pointers which have not been allocated yet. This patch initializes those pointers to NULL and allocates them only the first time. This way we can get rid of free calls in halt callback. This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains. Signed-off-by: Javier Martin <javier.martin@vista-silicon.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* mxc_fec: fix some erroneous PHY accesses.javier Martin2009-11-11-3/+5
| | | | | | | | | | | | | | | This patch fixes erroneous access to the ethernet PHY which broke the driver. 1. Selector field in the auto-negotiation register must be 0x00001 for using 802.3, not 0x00000 which is reseved. 2. Access to the PHY address specified by CONFIG_FEC_MXC_PHYADDR, not 0x0 fixed address. This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains. Now using proper defines for auto-negotiation register.
