62 * work around a bug in the Boot ROM of PH1-sLD3, LD4, Pro4, and sLD8:
64 * The boot ROM in these SoCs breaks the PARTITION_CONFIG [179] of
65 * Extended CSD register; when switching to the Boot Partition 1, the
66 * Boot ROM should issue the SWITCH command (CMD6) with Set Bits for
67 * the Access Bits, but in fact it uses Write Byte for the Access Bits.
68 * As a result, the BOOT_PARTITION_ENABLE field of the PARTITION_CONFIG
69 * is lost. This bug was fixed for PH1-Pro5 and later SoCs.
71 * Fixup mmc->part_config here because it is used to determine the
72 * partition which the U-Boot image is read from.
