I'm having some trouble using the platform device support for the MPC8245 using memory map B, set up using mpc10x_bridge_init(). When that function registers the host bridge it registers addresses 0x80000000-0xfebfffff for the bridge but by default (with EUMB mapped to MPC10X_MAPB_EUMB_BASE) the platform devices on the chip are also within this address range. The problem I'm seeing is that when platform_device_register() comes to call request_resource() on the devices that call fails because the addresses have already been allocated to the PCI host bridge.
I'm sure I must be missing something really obvious about how this is supposed to work but I can't for the life of me see what. Changing the platform code to use insert_resource() rather than request_resource() allows the devices to register and be used but that seems rather too drastic to be it. Thanks for any help. -- "You grabbed my hand and we fell into it, like a daydream - or a fever."
