Thomas Bogendoerfer c0de00b286 MIPS: SGI-IP22/28: Use PROM for memory detection ... EARLY_PRINTK uses ArcWrite (via prom_putchar) on IP22/28, which needs to not mess up PROMs data structures. ARC PROM gives out a list of memory chunks, which are used and which are free. This fixes the problem of not working early printk. By using XKPHYS spaces more than 256MB memory on Indigo2 R4k machines is working now, too.
