The CPU accessible DMA pool is general and not used only for PQ.
Accordingly, this patch rename the "free_cpu_pq_pool" label with
"free_cpu_accessible_dma_pool".

Where there is a spike in the CPU consumption, it may cause
random failures in the C/I since the KMD timeout for CPU
and/or QMAN0 jobs expires and it stops communicating to the simulator.
This commit fixes it by increasing timeout on polling functions
if working with simulator.

After removing the parsing of the command submission
when doing memset of the device memory, goya_validate_dma_pkt_host
is never called by the kernel, so there is no need to check
context id.

use_virt_addr member was used for telling whether to treat the
addresses in the CB as virtual during parsing. We disabled it only
when calling the parser from the driver memset device function,
and since this call had been removed, it should always be enabled.

Routing device accesses to the host memory requires the usage of a base
offset, which is canceled by the iATU just before leaving the device.
The value of the base offset might be distinctive between different ASIC
types.
The manipulation of the addresses is currently used throughout the
driver code, and one should be aware to it whenever providing a host
memory address to the device.
This patch removes this manipulation from the driver common code, and
moves it to the ASIC specific functions that are responsible for
host memory allocation/mapping.

This patch renames four functions in the ASIC-specific functions section,
so it will be easier to differentiate them from the generic kernel
functions with the same name.
This will help in future code reviews, to make sure we don't use the
kernel functions directly.

There is no need to parse the command submission when doing memset
of the device memory using the DMA engine because only the driver calls
the memset function and therefore, the CS is trusted and doesn't require
validation and patching.

The device's CPU accessible memory on host is managed in a dedicated
pool, except for 2 regions - Primary Queue (PQ) and Event Queue (EQ) -
which are allocated from generic DMA pools.
Due to address length limitations of the CPU, the addresses of all these
memory regions must have the same MSBs starting at bit 40.
This patch modifies the allocation of the PQ and EQ to be also from the
dedicated pool, to ensure compliance with the limitation.

This patch changes the ASIC interface function that changes the DRAM bar
window. The change is to return the old address that the DRAM bar pointed
to instead of an error code.
This simplifies the code that use this function (mainly in debugfs) to
restore the bar to the old setting.
This is also needed for easier support in future ASICs.

This patch slightly changes the macros of RREG32 and WREG32, which are
used when reading or writing from registers.
Instead of directly calling a function in the common code from these
macros, the new code calls a function from the ASIC functions interface.
This change allows us to share much more code between real ASICs and
simulators, which in turn reduces the maintenance burden and
the chances for forgetting to port code between the ASIC files.
The patch also implements the hl_poll_timeout macro, instead of calling
the generic readl_poll_timeout macro. This is required to allow use of
this macro in the simulator files.
As a result from this change, more functions in goya.c are shared with the
simulator and therefore, should not be defined as static.

This patch adds missing fields of start address 0 and 1 in the bmon
parameter structure that is received from the user in the debug IOCTL.
Without these fields, the functionality of the bmon trace is broken,
because there is no configuration of the base address of the filter of the
bus monitor.

This patch re-factors goya_parse_cb_no_ext_queue() to make it more
readable by inverting the check inside the first if statement so the bulk
of the function won't be inside an if statement.

pr_fmt() should be defined before including linux/printk.h, either
directly or indirectly, in order to avoid redefinition of the macro.
Currently the macro definition is in habanalabs.h, which is included in
many files, and that makes the addition/reorder of includes to be prone
to compilation errors.
This patch cancels this dependency by defining the macro only in the few
source files that use it.

Since CoreSight hardware topology can use a 'hidden' funnel in the
trace data path, this kind funnel doesn't have register for accessing
and is used by default from hardware design perspective. Below is an
example for related hardware topology:
+------+ +------+
| cpu0 |->| ETM |-\
+------+ +------+ \-> +--------+ +-----+
...... | Funnel |->| ETF |-\ Hidden funnel
+------+ +------+ /-> +--------+ +-----+ \ |
| cpu3 |->| ETM |-/ \ V
+------+ +------+ \-> +--------+
| Funnel |-> ...
+------+ +------+ /-> +--------+
| cpu4 |->| ETM |-\ /
+------+ +------+ \-> +--------+ +-----+ /
...... | Funnel |->| ETF |-/
+------+ +------+ /-> +--------+ +-----+
| cpu7 |->| ETM |-/
+------+ +------+
The CoreSight funnel driver only supports dynamic funnel with
registration register resource, thus it cannot support for the static
funnel case and it's impossible to create trace data path for this case.
This patch is to extend CoreSight funnel driver to support both for
static funnel and dynamic funnel. For the dynamic funnel it reuses the
code existed in the driver, for static funnel the driver will support
device probe if without providing register resource and the driver skips
registers accessing when detect the register base is NULL.

Following the same fashion with replicator DT binding, this patch is to
unify the DT binding for funnel to support static and dynamic modes;
finally we get the funnel DT binding as below:
Before patch:
Static funnel, aka. non-configurable funnel:
Not supported;
Dynamic funnel, aka. configurable funnel:
"arm,coresight-funnel", "arm,primecell";
After patch:
Static funnel:
"arm,coresight-static-funnel";
Dynamic funnel:
"arm,coresight-dynamic-funnel", "arm,primecell";
"arm,coresight-funnel", "arm,primecell"; (obsolete)
At the end of this patch, it gives an example for static funnel DT
binding, and updates the dynamic funnel example.

CoreSight uses below bindings for replicator:
Dynamic replicator, aka. configurable replicator:
"arm,coresight-dynamic-replicator", "arm,primecell";
Static replicator, aka. non-configurable replicator:
"arm,coresight-replicator";
The compatible string "arm,coresight-replicator" is not an explicit
naming to express the replicator is 'static'. To unify the naming
convention, this patch introduces a new compatible string
"arm,coresight-static-replicator" for the static replicator; the
compatible string "arm,coresight-replicator" is kept for backward
compatibility, but tag it as obsolete and suggest to use the new
compatible string.
As result CoreSight replicator have below bindings:
Dynamic replicator:
"arm,coresight-dynamic-replicator", "arm,primecell";
Static replicator:
"arm,coresight-static-replicator";
"arm,coresight-replicator"; (obsolete)
