powerpc/powernv: Support for OPAL console 2011-09-20T06:09:54+00:00 Benjamin Herrenschmidt benh@kernel.crashing.org 2011-09-19T17:44:59+00:00 daea1175a9f0f70eab5b33e2827d57ba8c686816 This adds a udbg and an hvc console backend for supporting a console using the OPAL console interfaces. On OPAL v1 we have hvc0 mapped to whatever console the system was configured for (network or hvsi serial port) via the service processor. On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL which generally corresponds to: hvc0 : network console (raw protocol) hvc1 : serial port S1 (hvsi) hvc2 : serial port S2 (hvsi) Note: At this point, early debug console only works with OPAL v1 and shouldn't be enabled in a normal kernel.

This adds a udbg and an hvc console backend for supporting a console
using the OPAL console interfaces.

On OPAL v1 we have hvc0 mapped to whatever console the system was
configured for (network or hvsi serial port) via the service
processor.

On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL
which generally corresponds to:

	hvc0 : network console (raw protocol)
	hvc1 : serial port S1 (hvsi)
	hvc2 : serial port S2 (hvsi)

Note: At this point, early debug console only works with OPAL v1
and shouldn't be enabled in a normal kernel.
