When using DM_I2C the speed value supplied to setup_i2c() is not used, so this code required CONFIG_SYS_MXC_I2C[12]_SPEED to be defined to compile, but did not actually use them. Change this so we no longer need to define an unused macro to compile in DM_I2C mode. Also make it more clear that they do not control the bus speed. Otherwise it is quite easy to mistakenly believe they are used to set the bus speed.

U-Boot for Wandboard -------------------- This file contains information for the port of U-Boot to the Wandboard. Wandboard is a development board that has three variants based on the following SoCs: mx6 quad, mx6 quad plus, mx6 dual lite and mx6 solo. For more details about Wandboard, please refer to: http://www.wandboard.org/ Building U-Boot for Wandboard ----------------------------- To build U-Boot for the Wandboard: $ make wandboard_config $ make Flashing U-Boot into the SD card -------------------------------- - After the 'make' command completes, the generated 'SPL' binary must be flashed into the SD card; $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync (Note - the SD card node may vary, so adjust this as needed). - Flash the u-boot.img image into the SD card: sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync - Insert the SD card into the slot located in the bottom of the board (same side as the mx6 processor) - Connect the serial cable to the host PC - Power up the board and U-Boot messages will appear in the serial console.
