Update of /cvsroot/src/sys/arch/hp300/hp300
In directory netbsd1:/var/slash-tmp/cvs-serv29010

Modified Files:
	locore.s 
Log Message:
A few small changes:
- Offset kernel text one page.  Stash the PA of this offset page for
  use later.
- Add a few comments.
- Free up some registers earlier in the initialization process.
- Use a `prototc' to set the Translation Control register, rather
  than relying on a2 pointing just past the MMU trampoline in the
  high page.  (Suggested by Charles Hannum.)
- Set VBR to the kernel vector table just before turning on the MMU.
- Just before rebooting, set VBR to 0, which is what the BOOTROM expects
  it to be.
