Johannes Berg 0479c19d9f iwlwifi: remove uCode alternatives mechanism
We've never released firmware using the alternatives
mechanism and our build process makes that difficult
anyway. This means that in every file we have ever
built (except maybe by hand for testing) the listed
alternative was 0. Make the alternative field in the
TLVs part of the TLV number (thus expanding that to
32 bits); this gives us more TLV numbers (not really
needed) and more importantly protects against rogue
firmware files that actually do use the alternatives
mechanism -- those will now be rejected since they
don't contain any valid TLVs.

David Spinadel 6dfa8d019c iwlwifi: change struct iwl_fw
Change iwl_fw struct to hold an array of fw_img instead of
three separated instances.

Change fw_img to hold an array of fw_desc instead of two
separate descriptors for instructions and data.

Change load_given_ucode, load_section, verification functions
etc. to support this structure.

David Spinadel ed8c8365c4 iwlwifi: Add TLVs and fields for 16.0 uCode
New TLVs for ucode sections that are not known as
instruction or data.

New TLVs for phy-configuration and default calibrations.

Add default calib and phy config fields to iwl_fw.

David Spinadel 0cedacc579 iwlwifi: more modularity in fw images and sections
Changed iwl_firmware_pieces structure to support an array of
separate images, and an array of sections for each image.

In fw_sec and fw_desc structures, added a field for
offset from the HW address, to support 16.0 uCode that
provides an offset instead of any other data about the section.
This field is filled with default values when parsing instruction
or data section.

Johannes Berg 3995deafda iwlwifi: rename ucode.h to fw-file.h
That name better reflects the contents
of the file and the fact that it isn't
related to iwl-ucode.c.

Johannes Berg 965974a631 iwlwifi: remove iwl-wifi.h
This file was recently introduced, but then
directly abused -- it contained private data
that shouldn't have been used by anything
but the implementation of firmware requests
and some very core code. Now that it is no
longer accessed by any code but the code in
iwl-drv.c, we can dissolve it.

Also rename the iwl_nic struct to iwl_drv to
better reflect where and how it is used.

Johannes Berg 0692fe41b3 iwlwifi: split out firmware store
Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.

Emmanuel Grumbach d0f76d6869 iwlwifi: virtualize the op_mode
Define the op_mode as an interface with its ops. All the functions
of the op_mode are "private", but its ops is made public in
iwl-op-mode.h.
The drv object starts the op_mode by using the start function in the
public ops.

Emmanuel Grumbach 6459f9871a iwlwifi: rename iwl_remove to iwl_op_mode_dvm_stop
iwl_remove stops the wifi flows, so rename.
Moreover, we can possibly stop the wifi flows even if the driver
is statically compiled in the kernel, so remove the __devexit pragma.

Emmanuel Grumbach 5c58edc63e iwlwifi: introducing the drv object's flows
Fetch the fw and spawn the op_mode. The op_mode that we need
to fetch is determined from the fw file.
Since the fw is fetched very early in the init flow, we can
determine what op_mode to spawn.
