When you say "end of the RAM', I think you mean higher addresses, i.e.
0xffff_ffff downwards or lower 0x000_0000 onwards? (this depends on
how to look at memory map, written on a sheet of paper -- straight or
upside down :-) ).

So the bottom line of PPC architecture is that it tries to have
unified booting/relocation process for every platform? For instance,
always copy itself in the upper addresses, occupying, say, 128kB or so
of RAM.

Well, you convinced me; but despite its flaws and drawbacks the
current ARM port architecture exists and it is here to stay for quite
awhile, unless there will be some hero ready to break it up and build
a new from scratch.
