Hello, A 'newbie-to-platform-devices' question:
In a patch that Kumar just sent for a compact flash device, the resource data (I/O addresses, IRQ # etc.) are retrieved from the platform system. I guess I can either modify the device tree in U-boot by adding additional nodes, or instantiate a platform device in Linux __init code based on static information. The former gives the advantage of having the bootloader pass the info to the OS. (Somebody please correct me if I'm off-base here!) Are device trees meant to only contain information about the CPU and tightly-coupled peripherals, or is it considered OK-form to also include board-level hardware info? I guess they can really hold anything, but I'm trying to figure out the original intent. regards, Ben
