[commit] r999 - trunk/openbios-devel/arch/sparc32

[repository service]

Author: mcayland

New Revision: 999
URL: http://tracker.coreboot.org/trac/openbios/changeset/999

Log:
Reduce memory of the Forth machine to 16k.

Since this memory is only being used by alloc-mem and free-mem then the majority of memory allocations will not actually be
taken from this pool but from the C malloc()/free() implementations instead.
