soc: qcom: Add snapshot of G-Link driver
This is a snapshot of the G-Link driver taken as of msm-4.4
commit <aaf356abef2> (Merge "scsi: ufs: add 2 lane support").
In addition, fix coding style issues, refactor usage
of waitqueue_active and remove BUG_ON() calls.

Support for the shared memory interface between the various
processors in the System on a Chip (SoC) which allows basic
inter-processor communication.

+config MSM_GLINK
+ bool "Generic Link (G-Link)"
+ help
+ G-Link is a generic link transport that replaces SMD. It is used
+ within a System-on-Chip (SoC) for communication between both internal
+ processors and external peripherals. The actual physical transport
+ is handled by transport plug-ins that can be individually enabled and
+ configured separately.
+
+config MSM_GLINK_LOOPBACK_SERVER
+ bool "Generic Link (G-Link) Loopback Server"
+ help
+ G-Link Loopback Server that enable loopback test framework to test
+ and validate the G-Link protocol stack. It support both local and
+ remote clients to configure the loopback server and echo back the
+ data received from the clients.

+ bool "Generic Link (G-Link) SMEM Native Transport"
+ help
+ G-Link SMEM Native Transport is a G-Link Transport plug-in. It allows
+ G-Link communication to remote entities through a shared memory
+ physical transport. The nature of shared memory limits this G-Link
+ transport to only connecting with entities internal to the
+ System-on-Chip.

+config MSM_GLINK_SPI_XPRT

+ tristate "Generic Link (G-Link) SPI Transport"
+ help
+ G-Link SPI Transport is a Transport plug-in developed over SPI
+ bus. This transport plug-in performs marshaling of G-Link
+ commands & data to the appropriate SPI bus wire format and
+ allows for G-Link communication with remote subsystems that are
+ external to the System-on-Chip.
+
+config TRACER_PKT
+ bool "Tracer Packet"
+ help
+ Tracer Packet helps in profiling the performance of inter-
+ processor communication protocols. The profiling information
+ can be logged into the tracer packet itself.
