bootinfo block in register r8. In locore.s we save the address in the global variable 'pa_bootinfo'. In machdep.c we compare this value against the hardwired address, but don't depend on its validity yet (ie: we still expect the bootinfo block to be at the hardwired address). After a small amount of time, we'll flip the switch and depend on the loader to pass us the address. From that moment on the loader is free to put it anywhere it likes, provided the machine itself likes it as well. Add some verbosity to aid in the transition. We emit a message if the loader didn't pass the address and we also emit a message if there's no bootinfo block at the hardwired address. While in locore.s, reduce the number of redundant serialization instructions. A srlz.i is a proper superset of a srlz.d and thus is a valid replacement. Also slightly reorder the movl instructions to improve bundle density. |
