firmware: tegra: Add BPMP debugfs support Tegra power management firmware running on the co-processor (BPMP) implements a simple pseudo file system akin to debugfs. The file system can be used for debugging purposes to examine and change the status of selected resources controlled by the firmware (such as clocks, resets, voltages, powergates, ...). Add support to "mirror" the firmware's file system to debugfs. At boot, query firmware for a list of all possible files and create corresponding debugfs entries. Read/write of individual files is implemented by sending a Message ReQuest (MRQ) that passes the full file path name and data to firmware via DRAM.

firmware: tegra: Add IVC library The Inter-VM communication (IVC) is a communication protocol which is designed for interprocessor communication (IPC) or the communication between the hypervisor and the virtual machine with a guest OS. Message channels are used to communicate between processors. They are backed by DRAM or SRAM, so care must be taken to maintain coherence of data. The IVC library maintains memory-based descriptors for the transmission and reception channels as well as the data coherence of the counter and payload. Clients, such as the driver for the BPMP firmware, can use the library to exchange messages with remote processors. Based on work by Peter Newman <pnewman@nvidia.com> and Joseph Lo <josephl@nvidia.com>.
