Comment(by Quozl):

 Is this to be XO-4 specific?  (the ''reg'' property of ''/asram'' is from
 the constant ''/audio-sram'' which is 131072 on MMP3, and 65536 on MMP2.)

 What is the value 2048 in the property?  Is it room for DMA descriptors or
 is it maximum period size?

 http://dev.laptop.org/~quozl/q7b29je.rom is a test build.

 http://dev.laptop.org/~quozl/z/1USPNn.txt is the working patch.

 The generated output is:
