To avoid completion timeouts during device boot, set up the

This also corrects the AX210 workaround to be done only on

We no longer need code that was introduced to differentiate
between two early versions of 8260.

We can remove this convoluted way to get the hardware version
that was needed because of a bug in the register's
configuration.

Moreover, since we no longer need to access the PRPH
registers, we no longer need to wake up the device,
request ownership, etc...
Remove all that.

This allows us to get the rid of the obsolete comment
about the AUX bus MISC address space which should have
been moved when this code was moved away from here.

8954e1eb22 iwlwifi: trans: Clear persistence bit when starting the FW
In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals.
The first PERST is expected and indicates the device on coming resume flow.
The second PERST causes FW restart FW restart.
In order to avoid this issue, the FW set the persistence bit on.
Once this bit is set, the FW ignores reset attempts.
The problem is when the FW gets assert during D3 and then the persistence
bit is set and causes the FW to ignore reset.
To handle this issue, the FW opens the preg bit which allows access
to the persistence bit, so that the driver clear the persistence bit
and reset the NIC.

The flow is as follows:
the driver checks if the persistence bit is set.
If the bit is set, the driver checks if he can clear the bit.
If the driver can not clear the bit then there is no point to continue
configuring the NIC since it will fail.

The fix was added is in start HW flow instead of the resume flow since in
general, if the persistence bit is set, the driver can not start the FW.
So it is good to check it when we start configuring the NIC.

The driver does not need to close the preg bit since the FW close it
during the start flow.

addce854f1 iwlwifi: mvm: fix firmware debug restart recording
When we want to stop the recording of the firmware debug
and restart it later without reloading the firmware we
don't need to resend the configuration that comes with
host commands.
Sending those commands confused the hardware and led to
an NMI 0x66.

Change the flow as following:
* read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL)
* clear those registers
* wait for the hardware to complete its write to the buffer
* get the data
* restore the value of those registers (to restart the
  recording)

For early start (where the configuration is already
compiled in the firmware), we don't need to set those
registers after the firmware has been loaded, but only
when we want to restart the recording without having
restarted the firmware.

5a4aa89552 iwlwifi: mvm: remove unneeded reg write in iwl_mvm_up()
Not only that this write is not needed (as FW does this
itself), on newer HW this register is write protected
so trying to write there will cause problems.

eda50cde58 iwlwifi: pcie: add context information support
Context information structure is going to be used in a000
devices for firmware self init.

The self init includes firmware self loading from DRAM by
ROM.
This means the TFH relevant firmware loading can be cleaned up.

The firmware loading includes the paging memory as well, so op
mode can stop initializing the paging and sending the DRAM_BLOCK_CMD.

Firmware is doing RFH, TFH and SCD configuration, while driver
only fills the required configurations and addresses in the
context information structure.

The only remaining access to RFH is the write pointer, which
is updated upon alive interrupt after FW configured the RFH.

This register is helpful for debugging D3 issues.
Driver turns all bits on, and then on exit reads the

76f8c0e17e iwlwifi: pcie: remove dead code
If device family is 8000 then iwl_pcie_load_cpu_sections()
won't be called at all (iwl_pcie_load_cpu_sections_8000() is
called in that case) so this piece of code never gets called.

54f315cb08 iwlwifi: pcie: Enable MSI mode when using MSI interrupts
On some of the chipsets MSI & INTA interrupts are disabled by default in
the HW registers, and need to be explicitly enabled to be used.

In case MSI-X isn't used, make sure MSI mode is enabled by setting
the relevant HW register.

To do so, support version 2 of shared memory cfg command, which
contains the sizes of the internal txfifos, and move the command
to the system group.

This includes requesting interrupt vectors from the OS,
