- * Boot ROM should issue the SWITCH command (CMD6) with Set Bits for
- * the Access Bits, but in fact it uses Write Byte for the Access Bits.
- * As a result, the BOOT_PARTITION_ENABLE field of the PARTITION_CONFIG
- * is lost. This bug was fixed for PH1-Pro5 and later SoCs.

- * Fixup mmc->part_config here because it is used to determine the
