The revision of the SoC the OPP is supported by.

This can be easily obtained from the datasheet of the

part being ordered/used. For example, it will be 0x01 for SR1.0

The eFuse bits that indicate the particular OPP is available.
58+
The device datasheet has a table talking about Device Speed Grades.
59+
This table is to be sorted with only the unique elements of the
60+
MAXIMUM OPERATING FREQUENCY starting from the first row which
61+
tells the lowest OPP, to the highest. The corresponding bits
62+
need to be set based on N elements of speed grade the device supports.
63+
So, if there are 3 possible unique MAXIMUM OPERATING FREQUENCY
64+
in the table, then BIT(0) | (1) | (2) will be set, which means
65+
the value shall be 0x7.
