| 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. |
