Change SPARC32 memory allocator to allocate memory starting from just below the OpenBIOS image downwards.

Browse Source 
The existing code appeared to be allocating memory from the wrong property (map rather than avail) and so rather than allocating 
memory starting from just below the OpenBIOS image downwards, it was simply reducing the reported size of the OpenBIOS image.
