      ahci: work around ATI SB600 h/w quirk · a878539e

      This addresses the recent ATI SB600 errata, where the hardware does
      not like 256-length PRD entries during FPDMA (aka NCQ).
      
      It hurts performance on SB600, but it is more important to get a
      correct patch eliminating the data corruption/lockups, and then later
      on tune for performance.
      
      We simply limit each command to a maximum of 255 sectors, on SB600.
