I've seen things like this in mpc8349emds code :

#if (CFG_DDR_SIZE != 256)
#warning Currenly any ddr size other than 256 is not supported
#endif

Is this reasonable ? Why ?

    
that's in the fixed sdram init code, which could be considered
reasonably unreasonable by some I suppose, since we can't guarantee the
fixed settings will work with whatever memory you decide to use with
it.  It should work with the memory that comes with the board, though.
  
fixed_sdram is ok - that's what I have and want to use.
I'm setting up the proper CFG_DDR_ defines in my header regarding the Manufacturer's spec.
btw, the spd code is being used by default on the 834x mds, not this
fixed_sdram stuff - it's mostly there for board porting completeness.

  
But it is known to work, isn't it ?
