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