Dafna Hirschfeld 0abcae8b48 habanalabs: add RMWREG32_SHIFTED to set a val within a mask
This is similar to RMWREG32, but the given 'val' is already shifted
according to the mask.
This allows several 'ORed' vals and masks to be set at once
The patch also fixes wrong usage of RMWREG32 by replacing
it with RMWREG32_SHIFTED

Marco Pagani 6825b5f81f habanalabs/gaudi2: added memset for the cq_size register
The clang-analyzer reported a warning: "Value stored to
'cq_size_addr' is never read".

The cq_size register of dcore0 is not being zeroed using
gaudi2_memset_device_lbw(), along with the other cq_* registers,
even though the corresponding cq_size_addr variable is set.

farah kassabri 18cd948204 habanalabs/gaudi2: change memory scrub mechanism
Currently the scrubbing mechanism used the EDMA engines by directly
setting the engine core registers to scrub a chunk of memory.
Due to a sporadic failure with this mechanism, it was decided to

Tomer Tayar 9c604af0c9 habanalabs/gaudi2: return to reset upon SM SEI BRESP error
Due to a H/W issue in the LBW path to the PCIE_DBI MSI-X doorbell, there
were false sporadic error responses in SM when it was configured to
write to there, and hence no reset was done as part of handling the
relevant event.
Now that the virtual MSI-X doorbell is used, such errors in SM are not
expected and reset shouldn't be skipped.

There is a possibility that the RAZWI initiator is not an engine. In

Tomer Tayar f0b6d3cc29 habanalabs/gaudi2: increase hard-reset sleep time to 2 sec
The access to the device registers is blocked during hard reset, until
preboot runs and allows the access to specific registers, including the
PSOC BTM_FSM register which is used to know when the reset is done.
Between the reset request and until this register is polled there is a
small delay of 500 msec which is not enough for F/W to process the reset
and for preboot to run, so the register might be accessed while it is
blocked.
To avoid it, increase the delay to 2 sec.

Ohad Sharabi 913bd4179b habanalabs: add return code field to module iterator

1. The need to "plant" return called in the private data. This is a
   drawback since the iterator itself should not be aware of the private
   data of the caller.
2. Due to 1 even in a failure the iterator would keep iterating instead
   of break upon error.

To overcome this an optional rc field added to the iterator context.

Dani Liberman 71386e11f2 habanalabs: removed seq_file parameter from is_idle asic functions
Change is_idle functions so it would be more usable outside debugfs.

Do this by replacing seq_file parameter with regular string.

Oded Gabbay a919b823ab habanalabs: move h/w dirty message to debug
H/W being dirty during initialization is completely expected in case
f/w tools are used before loading the driver. As it is not an error,
and as it doesn't give any meaningful information to the user,
no point of printing it.
