IPQ8074 has efuses like other Qualcomm SoC-s that are required for
determining various HW quirks which will be required later for CPR etc,
so lets add the QFPROM node for start.
Individidual fuses will be added as they are required.

From the HW document, I see the overall size of this region is 0x2000,
any reason to stick with 0x1000?
Like always, I dont have access to docs and 0x1000 is all I could find
downstream
being used.
Any chance you can share the regions inside of QFPROM, it would be great to use
the ECC corrected one if available.
Sorry, What do you refer by "ECC corrected" here?
Isnt there a corrected region in the QFPROM meant for reading?
As far as I understand it's protected by FEC.
Yes, there are two regions for the QFPROM, the region which you used
here is the one used for reading and there is a error correction logic
for it and it is size is 8KB not 4KB.
