51	  SDRAM configuration for group 0. The value depends on the
52	  hardware configuration. The default value is suitable
53	  for 32 MB organized as two 16 bits chips (e.g. Axis
54	  part number 18550) connected as one 32 bit device (i.e. in

71	  SDRAM timing parameters. The default value is ok for
72	  most hardwares but large SDRAMs may require a faster
73	  refresh (a.k.a 8K refresh). The default value implies
74	  100MHz clock and SDR mode.

92	  There are some guidelines though - if you know that only LED's are
93	  connected to port PA, then they are usually connected to bits 2-4
94	  and you can therefore use 1c.  On other boards which don't have the
95	  LED's at the general ports, these bits are used for all kinds of
96	  stuff.  If you don't know what to use, it is always safe to put all
