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.
