2017-07-12dm: mmc: fsl_esdhc: handle vqmmc supplyPeng Fan
Handle vqmmc supply. Some boards have a fixed I/O voltage at 1.8V for emmc, so the usdhc also needs to be configured as 1.8V by setting VSELECT bit. The vs18_enable is the one that used to checking whether setting VSELECT or not in the driver. So if vqmmc supply is 1.8V, set vs18_enable, the driver will set VSELECT.

2017-07-12mmc: fsl_esdhc: introduce vs18_enable for 1.8V fix I/OPeng Fan
When using eMMC with 1.8V I/O, the VSELECT bit need to be set in the USDHC controller when init. This patch adds a parameter "vs18_enable" in fsl_esdhc_cfg structure and priv data, so each controller can have different settings. We could not use CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT, it has problem that it will apply to all USDHC controllers and it only set the 1.8V at init phase. So if user does not select to the eMMC device, the voltage on the I/O pins are not correct.

2017-07-12net: fec_mxc: fix PHY initialization bug with CONFIG_DM_ETHLothar Waßmann
When CONFIG_DM_ETH is set, the FEC ethernet controller is reset after the PHY has been set up and initialzed. This breaks the communication with the PHY and results in an inoperable ethernet interface. Do the initialization with CONFIG_DM_ETH in the same order as with legacy ETH support to fix this.

DTB is encoded in big endian. When we retrieve property values, we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion. This is a bit error-prone, but sparse is useful to detect endian mismatch. We need to use (fdt32_t *) instead of (u32 *) for a pointer of a property value.
