pSeries machines when partitioned support a hypervisor virtual
console. This driver allows each pSeries partition to have a console
which is accessed via the HMC.

no other console mechanism exist but udbg, to get you a quick
console for userspace. Do NOT enable in production kernels.

This console uses the JTAG DCC on [31mCONFIG_ARM[0m to create a console under the HVC
driver. This console is used through a JTAG only on [31mCONFIG_ARM[0m. If you don't have
a JTAG then you probably don't want this option.

Partitionable IBM Power5 ppc64 machines allow hosting of
firmware virtual consoles from one Linux partition by
another Linux partition. This driver allows console data
from Linux partitions to be accessed through [31mCONFIG_TTY[0m device
interfaces in the device tree of a Linux partition running
this driver.
To compile this driver as a module, choose [31mCONFIG_M[0m here: the
module will be called hvcs. Additionally, this module
will depend on arch specific APIs exported from hvcserver.ko
which will also be compiled when this driver is built as a
module.
