2013-01-28net: fec_mxc: only call phy_connect in fec_probeTroy Kisky
This allows us to create the phydev before calling fec_probe in later patch. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

2013-01-28phy: add phy_find_by_mask/phy_connect_devTroy Kisky
It is useful to be able to try a range of possible phy addresses to connect. Also, an ethernet device is not required to use phy_find_by_mask leading to better separation of mii vs ethernet, as suggested by Andy Fleming. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-01-28net: fec_mxc: have fecmxc_initialize call fecmxc_initialize_multiTroy Kisky

2013-01-28net: fec_mxc: change fec_mii_setspeed parameterTroy Kisky
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.

2013-01-28net: fec_mxc: delete CONFIG_FEC_MXC_MULTITroy Kisky

2013-01-28mx6qsabre_common: Let mmc partition be board specificFabio Estevam
commit 49ea0ff5 (49ea0ff5) introduced CONFIG_SYS_MMC_ENV_PART into mx6qsabresd.h to store the mmc partition, but in order for it to have effect we should place it into 'mmcpart' variable. Also add CONFIG_SYS_MMC_ENV_PART into mx6qsabreauto.h. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

2013-01-22imximage.cfg: run files through C preprocessorTroy Kisky
The '#' used as comments in the files cause the preprocessor trouble, so change to /* */. The mkimage command which uses this preprocessor output was moved to arch/arm/imx-common/Makefile .gitignore was updated to ignore .cfgtmp files. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

2013-01-21mxs: ssp: Pull out the SSP bus to regs conversionMarek Vasut
Create function which converts SSP bus number to SSP register pointer. This functionality is reimplemented multiple times in the code, thus make one common implementation. Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.
