[mpeg2] ADSPCodeLoad failure continued

[Frank M. Siegert <frank@this.net>]

Can anyone tell me how the ADSPWriteAddress and ADSPWrite/ReadData 
interface works? I worked under the assumption that you need to

1. first write in the address using ADSPWriteAddress
2. then fetch data with ADSPReadData or write data with ADSPWriteData 
respectively.

So I included a small for loop in the code that a) reads the complete 16bit 
wide address space, it was all 0xffff , writing anything using the 
WriteData call does not change anything, in fact ADSPReadData always 
returns 0xfffff.

I disabled everything I could in the BIOS and removed any extra PCI 
hardware from the system, except for the AGP videocard. Still its fails to 
load the ADSP MC.

I included udelays (tried 3,5,10) in the ADSPCodeLoad function for every 
WriteAddress and Read/WriteData, still a NoGo.

I checked and rechecked the md5sum of the ADSP microcode, its fine.

I checked that the ADSP file was loaded in memory ok, before it was dumped 
into the ADSP, this worked ok.

Kfir/Altera Microcode is loaded ok, only the ADSP_KfInit fails - I would 
sort of understand if it does not work at all but this partly working state 
is annoying.

What options do I have left?
