      1 Freescale esdhc-specific options
      2 
      3 	- CONFIG_FSL_ESDHC_ADAPTER_IDENT
      4 		Support Freescale adapter card type identification. This is implemented by
      5 		operating Qixis FPGA relevant registers. The STAT_PRES1 register has SDHC
      6 		Card ID[0:2] bits showing the type of card installed in the SDHC Adapter Slot.
      7 
      8 		SDHC Card ID[0:2]	Adapter Card Type
      9 		0b000			reserved
     10 		0b001			eMMC Card Rev4.5
     11 		0b010			SD/MMC Legacy Card
     12 		0b011			eMMC Card Rev4.4
     13 		0b100			reserved
     14 		0b101			MMC Card
     15 		0b110			SD Card Rev2.0/3.0
     16 		0b111			No card is present
     17 	- CONFIG_SYS_FSL_ESDHC_LE
     18 		ESDHC IP is in little-endian mode. Accessing ESDHC registers can be
     19 		determined by ESDHC IP's endian mode or processor's endian mode.
     20 	- CONFIG_SYS_FSL_ESDHC_BE
     21 		ESDHC IP is in big-endian mode. Accessing ESDHC registers can be determined
     22 		by ESDHC IP's endian mode or processor's endian mode.
