The IVC code is library code that other drivers need to select if they need that library. However, if the symbol is user-selectable this can lead to conflicts. Fix this by making the symbol only selectable for COMPILE_TEST and add a select TEGRA_IVC to TEGRA_BPMP, which is currently the only user.

IVC (Inter-VM Communication) protocol is part of the IPC

(Inter Processor Communication) framework on Tegra. It maintains the

data and the different communication channels in SysRAM or RAM and

keeps the content is synchronization between host CPU and remote

processors.

BPMP (Boot and Power Management Processor) is designed to off-loading
|
|
the PM functions which include clock/DVFS/thermal/power from the CPU.
|
|
It needs HSP as the HW synchronization and notification module and
|
|
IVC module as the message communication protocol.
|
|
|
|
This driver manages the IPC interface between host CPU and the
|
|
firmware running on BPMP.
