Yes, the location is correct.

May you please go through marvell bootloader code (if you have), I hope they might have hardcoded the messages.

Prafulla,

This is what I see...

On mainlined u-boot, device id is read from the PCIE_Express_Vendor_Device_ID register (offset 0x4000)

But is this the correct location?

So it should display whatever value this register has.

As per specification it should display 6192 (in your case)

May be on this device 6192 this register reflects wrong value, in Marvell’s u-boot there may be some code tweak to display correct value.

BTW: mainlined u-boot supports 6192 just for basic boot operation (I don’t have a board based on 6192 :–( ).

Patches are welcomed to extend it’s support.

Is there a most-recent Errata document that you can point me to?

I've got the 819x Hardware Specifications docs from December 2008, but for instance, the MPP Function Summary doesn't agree w/ what posted in mainline; most of it is the same, but some parts are different.

Maybe you have a link?

regards and thanks,
