| - CONFIG_FSL_ESDHC_ADAPTER_IDENT | |
| Support Freescale adapter card type identification. This is implemented by | |
| operating Qixis FPGA relevant registers. The STAT_PRES1 register has SDHC | |
| Card ID[0:2] bits showing the type of card installed in the SDHC Adapter Slot. | |
| SDHC Card ID[0:2] Adapter Card Type | |
| 0b000 reserved | |
| 0b001 eMMC Card Rev4.5 | |
| 0b010 SD/MMC Legacy Card | |
| 0b011 eMMC Card Rev4.4 | |
| 0b100 reserved | |
| 0b101 MMC Card | |
| 0b110 SD Card Rev2.0/3.0 | |
| 0b111 No card is present | |
| - CONFIG_SYS_FSL_ESDHC_LE | |
| ESDHC IP is in little-endian mode. Accessing ESDHC registers can be | |
| determined by ESDHC IP's endian mode or processor's endian mode. | |
| - CONFIG_SYS_FSL_ESDHC_BE | |
| ESDHC IP is in big-endian mode. Accessing ESDHC registers can be determined | |
| by ESDHC IP's endian mode or processor's endian mode. | |
| - CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT forces to run at 1.8V. |
