Arnd Bergmann 4ddb1bf1a8 tegra: mark BPMP driver as little-endian only
The BPMP firmware driver never worked on big-endian kernels, and
cannot easily be made portable. Add a dependency to make this clear
in case anyone ever wants to try a big-endian kernel on this hardware.

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.

help
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.
