I'm not sure how devicetree is implemented for the PCI stuff, maybe the guys in the devicetree mailing list can help. Any tips guys ? Anyway, when I actually figure out a nice way to allocate fifo space based on enabled endpoints, I believe most users will just start setting that flag because it's far better to use the FIFO for enabled endpoints then not allocate it at all (image a situation where we have 4 IN eps and 1024 bytes FIFO space for each one of them, if we're running with only 1 IN ep enabled, we could allocate all 4x 1024 to the only enabled endpoint). -- balbi
