Benno Rice	5244eac968	Complete rework of the PowerPC pmap and a number of other bits in the early ... boot sequence. The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors) which is 70% faster than the older code that the original pmap.c was based on. It has also been based on the framework established by jake's initial sparc64 pmap.c. There is no change to how far the kernel gets (it makes it to the mountroot prompt in psim) but the new pmap code is a lot cleaner. Obtained from: NetBSD (pmap code)	2002-02-14 01:39:11 +00:00
Mark Peek	5fd2c51edb	Update PowerPC MD code to compile and do initial bootstrap based on ... recent changes (KSE and VM requiring physmem to be setup). Reviewed by: benno, jhb, julian	2001-09-20 00:47:17 +00:00
Benno Rice	d27f1d4c12	This commit (along with one pending in sys/dev/ofw and one in sys/conf) give ... us our first minimal glimpse of PowerPC support. With this code we can get to the "mountroot>" prompt on my Apple iMac. We can't get any further due to lack of clock and interrupt handling, among other things. This does however mean that pmap and VM are initialising. We're fairly dependant on OpenFirmware at this point, but I hope to add support for other classes of firmware at a later stage.
