It seems in double buffer mode the Blackfin MUSB controller
needs about 50us delay between the packet RX interrupt and RX

the MUSB RX buffer. Single buffer mode has no such problem.
So, we are looking for a way to set up single buffer mode
under MUSB framework if the original patch against 1.9 and
less MUSB version doesn't work for others.
Yes,to disable double buffering is the original purpose of my patch.
And since there is no control bits to implement it,we have to do this.
would you please dump the fifo configuration table from hw.
Sorry, I am not sure of your mean.
I meant, can you dump the contents of that address space ? RXMAXP/TXMAXP
etc ??
