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. 25
