1Freescale 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.
23
24	- CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT forces to run at 1.8V.
