[PATCH 0/3] Enable serial console for PReP machines

[Mark Cave-Ayland]

This patchset, when applied against Hervé's QEMU raven branch, provides a basic
serial console for PReP machines when launched from QEMU with -nographic.

There is still some further work to be done with setting up a proper ISA bridge
device but it seemed worthwhile handling the required console changes first as 
a self-contained patchset.

Mark Cave-Ayland (3):
  libopenbios: move console selection from compile-time to runtime
  escc/pc_serial: separate uart_* functions into separate namespaces
  ppc: enable basic PReP serial console
