Yangbo Lu5a8dbdc2015-04-22 13:57:00 +08003 - 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.

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.
