Do we need this or can this be recognized as a SFDP flash ?

The error is
"cadence-qspi ff8d2000.spi: unrecognized JEDEC id bytes: 20, bb, 22"
which is fixed with this table addition. Is there a better way to handle

Thanks for reviewing and the reply.

Seems like even with the SFDP parsing in place, we still need to track
the supported IDs, oh well.
