Currently, buffers from multiple flows pass through the same infra.
This way, in logs, we are unable to distinguish between buffers that
came from separate flows.
To address this problem, add a "topic" to buffer behavior
descriptor - a string identifier that will be used to identify in logs
the flow this buffer relates to.

Scenario:
1. During hard reset, driver executes device_kill_open_processes.
2. Drivers file descriptor is not closed yet (user process is alive),
hence we are starting loop on all open file descriptors.
3. Just before getting task struct of user process, according to
pid, SIGKILL is sent to the user process, hence get_pid_task
fails, driver prints a warning and device_kill_open_processes
returns an error.
4. Returned error causing driver fini do disable the device object
of the process which causes a kernel crash.
The fix is to handle this case not as an error and continue fini flow
as normal, since the killed process (by the SIGKILL) will release its
resources just like it will do when the driver sends him the sigkill.

Add the ability to scrub the device memory with a given value.
Add file 'dram_mem_scrub_val' to set the value
and a file 'dram_mem_scrub' to scrub the dram.
This is very important to help during automated tests, when you want
the CI system to randomize the memory before training certain
DL topologies.

Putting object by its handle and not by object pointer is useful in

The new unified memory manager uses page offset to pass buffer handle
during the mmap operation. One problem with this approach is that it
requires the handle to always be divisible by the page size, else, the
user would not be able to pass it correctly as an argument to the mmap
system call.
Previously, this was achieved by shifting the handle left after alloc
operation, and shifting it right before get operation. This was done in
the user code. This creates code duplication, and, what's worse,
requires some knowledge from the user regarding the handle internal
structure, hurting the encapsulation.
This patch encloses all the page shifts inside memory manager functions.
This way, the user can take the handle as a black box, and simply use
it, without any concert about how it actually works.

Currently we're using the same poll interval value for both

and the device CPU boot phases status waits.
On COMMs protocol this interval should be much lower than the
device CPU boot which may take long time to change status.

This patch let the user decide whether the translations done in the
page tables will be fetched directly to the STLB right after the map.
We want to let the user control whether to perform prefetch upon map
operation.
To do so a memory flag was added, to be used in the MAP ioctl, called
HL_MEM_PREFETCH and if set- the mappings will be fetched directly to
the STLB after map operation.

The habanalabs HW requires memory resources to be used by its
internal hardware structures. These structures are allocated and
initialized by the driver. We would like to use the device HBM for
that purpose. This memory is io-remapped and accessed using the
writel()/writeb()/writew() commands.
Since some of the HW structures are one byte in size we need to
add support for the writeb() and readb() functions in the driver.

Instead of using for_each_sg when iterating sgt that contains dma
entries, use the more proper for_each_sgtable_dma_sg macro.
In addition, both Goya and Gaudi have the exact same implementation
of the asic function that encapsulate the usage of this macro, so
it is better to move that implementation to the common code.

This is a part of overall refactoring attempt to separate nic and the
core drivers.
Currently, there are 4 different flows, that contain very similar code.
These are the ts, nic, hwblocks and cb alloc/map flows. The similar
aspect of all these flows is that they all contain a central store, with
memory buffers inside, supporting the following set of operations:
- Allocate buffer and return handle
- Get buffer from the store with handle
- Put the buffer (last put releases the buffer)
- Map the buffer to the user
This patch contains a generic data structure used to implement the above
memory buffer store interface. Conversion of the existing code to use
the new data structure will follow.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

The default max power is deduced from the card type value in the CPU-CP
info. This value is then set in the max power variable of the device
structure.
Getting the CPU-CP info is done as part of the late init phase
which is called also during reset. This means that a max power value
which is modified via sysfs will be reset during hard reset back to the
default value.
As the max power is updated in any case during device init in
hl_sysfs_init(), this setting in late init can be removed, and the
overriding during reset is thus avoided.

As per the current implementation only single callback data gets saved per
event, driver is throwing an error if try to register multiple callback for
same event. So at time of unregistration of any event required things are
event details and callback handler as parameter of xlnx_unregister_event().
As part of adding support of multiple callbacks for same event also require
change in prototype of xlnx_unregister_event().
During unregistration of any events, now required things are event details,
callback handler and agent's private data as parameter of
xlnx_unregister_event().
Also modify the usage of xlnx_unregister_event() in xilinx/zynqmp_power.c
driver as per new implementation.
