Title:
Add RevID field to VPD info in EEPROM
Status in linux-bluefield package in Ubuntu:
Fix Committed
Bug description:
SRU Justification:
[Impact]
Currently, the VPD info stored in the EEPROM does not include a Rev ID. This
field is incremented when a PN goes through minor HW changes. Sometimes, SW
needs to differentiate the two versions of the card. Hence, this field should
be supported in the EEPROM MFG partition.
[Fix]
EC (Engineering Changes) field is used to denote the HW Revision of a PN. Add
it to the EEPROM MFG and provide a sysfs entry to access the same via
mlx-bootctl.
[Test Case]
This field is typically programmed at the manufacturing step using the bfcfg
tool which uses the write mechanism in the driver and then the MFG partition is
locked. Reading the "rev" sysfs will show the current value.
[Regression Potential]
Can be considered minimum.
