When excuting a command like: modprobe ipmi_si ports=0xffc0e3 type=bt The system would get an oops. The trouble here is that ipmi_si_hardcode_find_bmc() is called before ipmi_si_platform_init(), but initialization of the hard-coded device creates an IPMI platform device, which won't be initialized yet. The real trouble is that hard-coded devices aren't created with any device, and the fixup is done later. So do it right, create the hard-coded devices as normal platform devices. This required adding some new resource types to the IPMI platform code for passing information required by the hard-coded device and adding some code to remove the hard-coded platform devices on module removal. To enforce the "hard-coded devices passed by the user take priority over firmware devices" rule, some special code was added to check and see if a hard-coded device already exists.
