5f9c1f8f9a wifi: iwlwifi: fw: fix compile w/o CONFIG_ACPI
The user of this function passes a pointer to a value that
doesn't exist when compiled w/o CONFIG_ACPI. Since we don't
need the value then, make the non-ACPI version a macro to
allow it to still build.

091d89428f wifi: iwlwifi: simplify getting DSM from ACPI
As DSMs are going to be read from UEFI too, we need a unified API
to get DSMs for both ACPI and UEFI.

The difference in getting DSM in each one of these methods (ACPI, UEFI)
is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM
values (8 or 32 for ACPI, 32 for UEFI).

Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which
determines the GUID, revision (these two are the same for all WiFi DSMs),
and size (based on a func-to-size mapping) internally.

While at it, fix DSM_FUNC_RFI_CONFIG to expect a 32-bit value
(as defined in Intel BIOS spec) and not a 8-bit one.

3bc67e7c18 wifi: iwlwifi: separate TAS 'read-from-BIOS' and 'send-to-FW' flows

This seems wrong, we should have the 'read-from-BIOS' flow
(iwl_acpi_get_tas in iwlwifi) reading/parsing/validating the table from
BIOS, and the 'send-to-FW' flow (iwl_mvm_tas_init) doing
all the FW versioning checks and cmd filling.
Move the cmd filling to the 'send-to-fw' flow.

All the regulatory tables from BIOS are going to be loaded
(preferably) from the UEFI instead of the ACPI.
There is a security issue with the fact that anyone can

The solution for that is to have a lock for all WIFI GUID UEFI
variables, and only if the UEFI variables are locked then we can
read it.
The status of the lock (unlocked, locked, test mode) is indicated
in a ACPI table: Guid Lock ACPI Indicator.
Load this table so the driver knows whether to read from UEFI or
not

In case of a conflict between BIOS version and FW
version of the PPAG table - the values arrive in the FW in the wrong
places. This happens because we're storing the table in different
structures depending on the BIOS version, not on the FW version,
and so the FW doesn't get what it expect to.
Always store the table in a v2 structure (which is a superset
of v1 and v0).

Also store the table in a structured way and in it's own structure,
rather then storing it in the ppag command structure, similarly to
the WRDS, EWRD and WGDS tables.

2a8084147b iwlwifi: acpi: support reading and storing WRDS revision 1 and 2
Change the SAR profile tables storage to revision 2 regardless of the
revision we read from ACPI.  Revision 2 is a superset of revision 1,
which is in turn a superset of revision 0, so they can all be stored
inside revision 2.

Add support for reading and storing also revisions 1 and 2, whose only
difference is the number of chains and number of sub-bands.  So most
of the code revolves around passing different chain and sub-band
sizes.

With this patch we still pass only revision 0 to the firmware, but
that will be changed in a separate patch.

45acebf8d6 iwlwifi: fix sar geo table initialization
When adding support for version 3 of the GEO_TX_POWER_LIMIT command,
the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).

So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.

Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.
