[PATCH 0/2] powerpc: Early debug console configuration clean up

[Alistair Popple]

This patch series (based on v3.9) adds a configuration option to
enable the use of BootX or OpenFirmware console for early debug
console support.

Previously the use of BootX/OpenFirmware as an early debug console was
selected by CONFIG_BOOTX. However this left the ability to select a
different early debug console under the "Early debugging" menu which
was not supported by udbg.c. Instead the actual console selected when
both CONFIG_BOOTX and another early debug console is conifigured was
based on the arbitrary order of a series of #if/#elif's in udbg.c.

This patch replaces the previously sent "[PATCH] Make CONFIG_BOOTX an
exclusive early debug option".
