New Revision: 857

Modified:
   coreboot-v3/lib/console.c
Log:
Fix initial printk buffer address initialization. This was broken in
r785 (move from explicit asm to implicit C) and unfortunately qemu never
triggered the bug, only real hardware did. That's because qemu will not
spew an error on access to RAM before RAM is enabled.

Thanks to Ron for bisecting this.
