loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months
