- 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.

- 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.
