SoCs and various chips (including, famously, their wifi chips.) This is "just" (all 20,000 lines of it) code to enumerate the various versions of busses inside these devices, including the PCI bridge and the direct SIBA bridge found in MIPS chips. It also includes shared code for some bus operations (suspend, resume, etc); EEPROM/SROM/etc parsing and other things that are shared between chips. Eventually this'll replace the code that bwi/bwn uses for the internal bus, as well as some apparently upcoming mips74k broadcom SoC support which uses bwn! Thanks to Landon Fuller <landonf@landonf.org> for all this work! Obtained from: https://github.com/landonf/freebsd/compare/user/landonf/bcm4331-CURRENT
