- unify sparc_bbinfo (1064 bytes, with 256 block entries) and sun68k_bbinfo (296 byte, with 64 block entries) into shared_bbinfo (512 bytes, with 118 block entries), which will be also shared by future bbinfo-using platforms (including macppc) - add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs bootxx version skew. - add macppc support */bootxx.c: - migrate to new shared_bbinfo structure installboot: - add macppc support (still needs applepartmap support and testing) - improve and add some more warnings & errors to installboot - implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which perform the majority of the work for bbinfo-using back-ends (rather than replicating that across multiple back-ends).
