[U-Boot-Users] PCI_REGION_MEMORY and prefetchable PCI windows?

[Kumar Gala]

I was wondering if the PCI_REGION_MEMORY had any real meaning.  I see a 
number of places in which its set, but none that actual use it for 
anyting.  The only thing I see it doing is ensuring that system memory has 
a unique 'flags' value from PCI memory.  Is this the intent?

Also, I'm starting to look at adding the ability to register a PCI memory 
region as prefetchable and handle allocations of devices that have BARs 
that are prefetchable.  I plan on modeling this after the code that 
handles pci_mem, any comments?

thanks
