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.

82ea79660c iwlwifi: pcie: use WFPM_GP for debugging D3 flows
This register is helpful for debugging D3 issues.
Driver turns all bits on, and then on exit reads the
updated value there.

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.

d6a2c5c78d iwlwifi: pcie: fix ucode load flow for a000 devices
Turns out we should access TFH relative addresses.
Also, the FH_UCODE_LOAD_STATUS was replaced by
UREG_UCODE_LOAD_STATUS.

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.

5b08641429 iwlwifi: mvm: support dumping UMAC internal txfifos
In case of FW error, support dumping the UMAC internal txfifos.
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.

2e5d4a8f61 iwlwifi: pcie: Add new configuration to enable MSIX
Working with MSIX requires prior configuration.
This includes requesting interrupt vectors from the OS,
registering the vectors and mapping the optional causes to the
relevant interrupt. In addition add new interrupt handler
to handle MSIX interrupt.
