ee0c53895 mmc: fsl_esdhc: Add support to force VSELECT set ... Browse Code »

Some boards cannot do voltage negotiation but need to set the VSELECT
bit forcely to ensure it to work at 1.8V.

This commit adds CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT flag for this use.

CONFIG_SYS_FSL_ESDHC_LE means ESDHC IP is in little-endian mode.
CONFIG_SYS_FSL_ESDHC_BE means ESDHC IP is in big-endian mode.
CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT forces to run at 1.8V.

Accessing ESDHC registers can be determined by ESDHC IP's endian
mode or processor's endian mode.
