65 | * work around a bug in the Boot ROM of PH1-sLD3, LD4, Pro4, and sLD8: | |
66 | * | |
67 | * The boot ROM in these SoCs breaks the PARTITION_CONFIG [179] of | |
68 | * Extended CSD register; when switching to the Boot Partition 1, the | |
69 | * Boot ROM should issue the SWITCH command (CMD6) with Set Bits for | |
70 | * the Access Bits, but in fact it uses Write Byte for the Access Bits. | |
71 | * As a result, the BOOT_PARTITION_ENABLE field of the PARTITION_CONFIG | |
72 | * is lost. This bug was fixed for PH1-Pro5 and later SoCs. | |
73 | * | |
74 | * Fixup mmc->part_config here because it is used to determine the | |
75 | * partition which the U-Boot image is read from. | |
