VR4131 - MQ1132 - UPD63335

["Suresh. R" <suresh@mistralsoftware.com>]

Hi,
  This might be a very basic question, but I am very new to this field. 
So please help me.
I am writing a linux device driver for UPD63335 audio codec. Its 
controlled through the MQ1132 co-processor. The VR4131 is the processor. 
The memory of MQ1132 is mapped to the processor memory in Kseg1 (0xA000 
0000 onwards) which the manual says is TLB Unmapped region. Now my 
question is is it necessary to map this region before using it in Linux. 
Actually I have WinCE code for my reference. In that code the programmer 
is mapping the region using Virtual Cpoy and Virtual Alloc. Is it 
necessary to do that or Can I directly address the memory locatoin.
Please help

Thanks in advance

Regards
Suresh
