Hello, I have a few large BARs from various PCI/PCIe devices and they exceeded my linear PCI mapping space on the ARM chip. The chip can only do 256MB mapping at the same time. I need map all devices at the same time so I can only assign a portion of certain large BARs, e.g DeviceX: BAR0=512MB --> only assigned 8M resource to it ... DeviceY: BAR2=512MB --->only assigned 16M resource to it BAR sizes are provided by hardware and they're read-only. I think the above map should not cause trouble, correct? DeviceX/DeviceY will use the 8M/16M window to address its whole 512M for inbound transaction without problems here. I'm hacking pci_read_base to decrease the size.
