OK.  So what I'm getting at is how is this different from other boards
where we say "Oh, this is $FOO, it has $X LPDRR2 RAM" and "Oh, this is
$BAR, it has $Y DDR3 RAM" ?  The only thing I'm able to think of is that
we cannot call get_ram_size() to see the _size_ of the RAM after doing
$whatever to see what board we're on and doing the right configuration
for the DDR controller or whatever.
