- changes for v2:
- change MUX_PAD_CTRL value for MX6_PAD_GPIO_16__ENET_REF_CLK
- set cs1 from ecspi4 to high
- add splash screen support
- add comment from Stefano babic:
- remove mxc_iomux_set_gpr_register instead use setbits_le32 remove patch http://patchwork.ozlabs.org/patch/353324/
from this patchserie, as no longer needed
- use for loop for calling enable_spi_clk()
- simplify board_mmc_getcd()
- simplify board_mmc_init()
- remove board_phy_config()
- remove setup_fec() and work code into board_eth_init()
- use define for i2c slave address
- remove udelay in board_ehci_hcd_init()
- remove CONFIG_SPL_BUILD, as this board does not use CONFIG_SPL_BUILD
- changes for v3:
- add comment from Stefano Babic:
- simplify setup_iomux_uart()
- remove enable_spi()
- remove enable wp pin for the st micron flash from board code to spi driver. Enable this new config option only in board config file
- use common functions from pwm modul
