Fix for: Sparse defects
Sparse stated that:
-symbol 'tegra_vpr1_dev' was not declared. Should it be static?
-symbol 'tegra_vpr_cma_dev' was not declared. Should it be static?
-symbol 'tegra_generic_cma_dev' was not declared. Should it be static?
-symbol 'tegra_vpr_dev' was not declared. Should it be static?
-symbol 'tegra_generic_dev' was not declared. Should it be static?
Making all the above functions static since it is being used in nvmap_init.c only.

CONFIG_TEGRA_BWMGR is a downstream solution in the kernel before
K5.15, and the implementation now is completed moved to BPMP side.
Since it is not supported anymore, remove the legacy code for
maintainability.

No client need the dram_clk_to_mc_clk, tegra_dram_types functions from
mc-utils. Hence remove these functions.
get_dram_num_channels is needed by resman team, hence update it to
return number of channels for t264.

mc-utils driver support is needed on T264, and it should be present in
nvidia-t264 repo, so as to avoid leaking any information. Also, we need
to make sure once T264 is public the existing mc-utils driver can be
updated easily for T264 support.
Hence first copy the existing mc-utils driver from nvidia-oot into
nvidia-t264, then make changes for T264 and finally when T264 is public,
just cherry-pick the addional changes in nvidia-oot and clean up driver
from nvidia-t264. This change is doing the first step i.e. copying
existing mc-utils driver code from nvidia-oot into nvidia-t264.

Remove some of the files which were added as optional for
non-existing of T264 patches. As T264 OOT drivers are
collapsing into the core tree, remove such optional files.

Current mc-utils driver is specific to T234 without any support for
extending it to future SOCs. Add such support so that it can be easily
extended for future chips.
- Create a struct of function pointers of all present operations
- Set these function pointers as per SOCs

For T23x, we have a separate R5 based cluster
named as Display Controller Engine(DCE) to run
our Display RM code. This driver will run on CPU
with the following functionality:
Via debugfs for test and bring-up purposes:
1. Reads the DCE firmware image into DRAM.
2. Sets up DCE AST to cover the DCE firmware image.
3. Sets up R5 reset vector to point to DCE firmware
entry point
4. Brings DCE out of reset
5. Dumps various regsiters for debug
In production env:
1. Manages interrupts to CPU from DCE
2. Uses bootstrap command interface to define Admin
IPC
3. Locks down bootstrap command interface
4. Uses Admin IPC to define message IPC
5. Uses Admin IPC to define message IPC payload area
6. Uses Admin IPC to set IPC channels
6. Uses Admin IPC to define crashdump area
(optional)
7. Provides IPC interfaces for any DCE Client running
on CCPLEX including Display RM.
8. Uses Admin IPC to set logging level (optional)
This patch puts a framework in place with the
following features :
1. Firmware Loading
2. AST Configuration
3. DCE Reset with EVP Programming
4. Logging Infra
5. Debugfs Support
6. Interrupt Handling
7. Mailbox Programming
8. IPC Programming
9. DCE Client Interface
10. Ftrace Support for debug purposes

Actmon is a hardware block that can be used to track the activity of
certain hardware units. It can boost EMC clock depending
on the memory traffic among various client. It is called central actmon
as it monitors central activity for example MC activity.
Add central activity monitor driver.
