Update on: MPC85xx git/MPC8548cds - PCI/PCIE problemS with Marvel SATA driver...

[Morrison, Tom]

Olof,

Are you saying that it must 'know' about the PCI id(s)
for this SATA card before it even probes that device???

Even though the module is compiled into the kernel and 
I've verified that:

  a) the pci scan bus has detected this device
  b) that the sata_mv driver is registering itself
     as a PCI Device driver?

????

Also, fyi, its also complaining about the PCI Express 
Root Bridge on the MPC8548 as an unknown device...

   manufacturer: 0x1957 (aka: Freescale)
   class: 0xFFFF

although that doesn't explain why the same PCI 
Express SATA card / ~same sata_mv driver on an 
Intel X86 platform doesn't get recognized either.

Thank you for any additional insight you have on this Olof!

Tom

A patch went into 2.6.20 quite late to add the PCI ids for at least
one 7042 controller (Highpoint). You might have to add the ids of your
controller as well.
