Explain what is different about "-pd" and why this new revision  
requires a separate compile-time target.

If it's due to raw DDR config, say so in the changelog.  Is there any  
way we could read a revision register to select the proper DDR config  
at runtime?

If it's due to different NAND page size, that will no longer be an  
issue once this is applied:

CONFIG_P1020RDB is not a good name to mean specifically the -PC  
revision.  Change it so that CONFIG_P1020RDB is set for all revisions  
of P1020RDB, and introduce CONFIG_P1020RDB-PC for PC-specific things.
