Oh. Well, besides the point that only 8 lines of my function are the
memory size probe (3 writes into memory and 1 read per bank) the
get_ram_size function doesn't address mapping of two banks once the
sizes are detected. That is where most of my effort went.

Also, Stefan Roese points out the cpu/ppc4xx/sdram.c file, but
that only handles 1 bank (and so obviously doesn't do mapping,
which is largely what I worried about) and uses hard coded timings
different from those appropriate for my board.

So I'll stick with my code for now, although  I'll keep a watch on
the changes that Stefan suggests are coming.

Thanks,
