The /proc/bus/nubus/s/ directory tree for any slot s is missing a lot of information. The struct file_operations methods have long been left unimplemented (hence the familiar compile-time warning, "Need to set some I/O handlers here"). Slot resources have a complex structure which varies depending on board function. The logic for interpreting these ROM data structures is found in nubus.c. Let's not duplicate that logic in proc.c. Create the /proc/bus/nubus/s/ inodes while scanning slot s. During descent through slot resource subdirectories, call the new nubus_proc_add_foo() functions to create the procfs inodes. Also add a new function, nubus_seq_write_rsrc_mem(), to write the contents of a particular slot resource to a given seq_file. This is used by the procfs file_operations methods, to finally give userspace access to slot ROM information, such as the available video modes.
