- * DECstation has one physical memory segment.

+ *   free list, since some TC boards (e.g. PixelStamp boards) are only able 
+ *   to DMA into this region, and we want them to have a fighting chance of
+ *   allocating their DMA memory during autoconfiguration.
+ *
+ * VM_PHYSSEG_NOADD
+ *   We can't add RAM after vm_mem_init.
