Currently, uniphier_get_soc_type() converts the SoC ID (this is read from the revision register) to an enum symbol to use it for SoC identification. Come to think of it, there is no need for the conversion in the first place. Using the SoC ID from the register as-is a straightforward way.

*
|
|
* The boot ROM in these SoCs breaks the PARTITION_CONFIG [179] of
|
|
* Extended CSD register; when switching to the Boot Partition 1, the
|
|
* 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
|
|
* partition which the U-Boot image is read from.
