    Missing details in Datasheets for Family F

    lautriv

      Hello there ,

      i'm about to port a board to coreboot and miss some details in the datasheets.

      the CPU(s) in question are a couple of 880 on socket 940 which report as

       

      Family 0F(15), Model 21(33), Stepping 2, Microcode 0x4d

       

      however, the Bios and Kernel Developer Guide for Family F does not even mention

      Socket 940, in particular the DramTimingRegister Low, offset 0x88 [31:24]

      is only declaring Sockets F, AM2, S1G1 and ASB1.

       

      Beeing stuck on that part, i assume there are further differences because

      this CPU Type is the last Fam_F using no DDR2 but DDR RAM.

       

      Any hints, links and details are appredicated.
