* Stuff for bootinfo interface versioning
*
* At the start of kernel code, a 'struct bootversion' is located.
* bootstrap checks for a matching version of the interface before booting
* a kernel, to avoid user confusion if kernel and bootstrap don't work
* together :-)
*
* If incompatible changes are made to the bootinfo interface, the major
* number below should be stepped (and the minor reset to 0) for the
* appropriate machine. If a change is backward-compatible, the minor
* should be stepped. "Backwards-compatible" means that booting will work,
* but certain features may not.
