Guest VM has access to all of the profiler carveout right now so that
it can read full carveout and dump all the entries.
Right now address and size of Guest VM owned profiler carveout is parsed
from kernel command line. And the address of full profiler carveout
(containing logs of other VMs too) is calculated based on assumptions.
Current architecture is now getting reworked so that only a privileged
Guest VM can access full carveout and that too in read-only mode. Each
VM will have read-write access to its own carveout to read/write
profiler entries of that VM.
Update tegra_bootloader_debug_init.c to parse tegra_bl_prof_ro_start and
tegra_bl_prof_ro_size from kernel command line. These values indicate
address and size of the full read only carveout.
In tegra_bootloader_debuginit(), map the address of read only carveout
to tegra_bl_mapped_prof_ro_start and set is_privileged_vm to true.
Only privileged VM will be assigned this read only address by BL.
tegra_bl_mapped_prof_start continues to map to read-write carveout
owned by the VM.
Update profiler_show() so that it reads entries from the read-only
carveout if is_privileged_vm is set, otherwise it reads from read
write carveout.

When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.
Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.
This allows us to by-pass debugfs initialization if debugfs
is not enabled.

Upstream Linux commit 4c1e0a97351a ("firmware: tegra: bpmp: Use
iosys-map helpers") updated the Tegra IVC driver to use the
iosys-map helpers for Linux v6.2. This causes the Tegra capture-ivc
driver build to fail. Temporarily disable the building of this driver
while this build issue is fixed. Stub functions are added to permit
other drivers that use this driver to build.

For dma mappings done with dma_map_sg() calls, dma_sync_sg* calls are
required in order to make sure that caches for all the scattered
addresses are synced. Using dma_sync_single* call for syncing caches
can access address which is not mapped by dma_sync_sg() and cause kernel
exceptions.
Fix this by using correct cache sync calls for appropriate dma mapping
APIs.

EMC registers are currently accessed to get DRAM parameters.
As these are platform specific and static, DRAM parameters are added in
device-tree. In case of hypervisor environment, read DRAM properties
from device-tree instead of accessing EMC registers.
Also, MC and EMC register access by kernel is going to be blocked from
hypervisor. So, remove access to these registers.

The mc-utils driver shares a Makefile with several others drivers in the
drivers/platform/tegra directory and this means that we cannot compile
the mc-utils driver independently of these other drivers and package the
mc-utils driver without all of the other drivers. Therefore, move the
mc-utils driver into its own sub-directory and add its own Makefile so
that we can build and package this driver independently.

making a fresh copy in nvdia-oot folder -
- hwpm is introduced from T234 onwards
- mc-hwpm is dependent on mc driver. nvidia-oot
uses upstream mc driver. Hence mc-hwpm should also
use upstream mc driver.
- Thats why porting changes needed in mc-hwpm driver
to be incompatible with upstream mc driver
