[pci] Performing burst readings

[Marco Buffa <marcobuffa@lombardiacom.it>]

I'm compiling a guest pci bridge.

I can't perform burst readings from wishbone bus, I've set the bits #1 
in the image control register (it's a memory image), but the transfer 
rate is the same (about 2.5 MB/s) :-(
I look the wb-master signals at the oscilloscope and I see that cyc_o 
falls every single transfer cycle, like stb_o does, and this should be 
wrong...
Should I perform a "memory read line/multiple" (page 31 of the "PCI IP 
Core Specification")? How can I do that?

I would like to increase the transfer rate up to 20MB/s... Someone 
succeded in this goal?

Thanks a lot.
