to ensure that execution of any platform-specific boot code can occur before the main "load & go" boot, even if they invoke
Forth commands that alter the parse buffer.

IEEE-1275 spec compliance.
This patch implements the following:
1) Fix bootpath/bootargs handling so that default values are read from NVRAM, and allow multiple space-separated values to be
specified.
2) With correct bootargs handling in place, move the ELF loader over to the new libopenbios unified loaders.
3) Remove all the loader code from all architecture directories sine we don't need it anymore.
4) Simplify the boot word so it invokes platform-specific code where required, then calls load and go as per the specification.
Tested on all my available images for SPARC32, SPARC64 and PPC, and compile-tested on x86.

arguments. With these fixes in place we can now switch the boot word to use (encode-bootpath) which means that the bootpath and
bootarg properties are now set exactly the same when executing boot and/or load.

SPARC64 and x86.

accordingly. Hence since the loaders are currently written in C, it makes more sense to drop down into C and re-use the same
code rather than have a second implementation in Forth.

This is the generic command, it needs support from the filesystem
packages.

This patch implements the following Forth words:
debug <xt> - Mark word for debugging
debug-off - Unmark all words for debugging
resume - Return from subordinate Forth interpreter
The source debugger also implements the following commands when it has
been activated:
Up - Unmark current word for debugging, mark parent and continue
Down - Mark next word for debugging
Trace - Continue execution until end of word displaying
debug information
Rstack - Display contents of the Rstack
Forth - Launch subordinate Forth interpreter
