Re: [coreboot] 16 GPUs on one board

I have had this issue in regards to SR-IOV, - at the moment coreboot 
only supports 32Bit MMIO unfortunately one can't have too many graphics 
devices or network interfaces apparently.

Considering the success of the OpenBMC port fund it would be nice if we 
could get a fund going to fix this if it wouldn't cost too much as I 
would really like to be able to use SR-IOV and many more PCI-e devices 
on my board via a cyclone PCI-e expansion system eventually.

I am not sure if there is a work-around in linux but post back if you 
find one.

16 GPUs on one board

Lets take a slight differently tactic. What would happen if we removed the
ROM from a GPU/NIC? Would the GPU's still require 256MB~304MB of PCI_MMIO?
