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.

8f7ffbe2b2 iwlwifi: avoid some operations if no uCode loaded
Printing the SRAM and similar testmode operations could
be triggered when no uCode is loaded; prevent those
invalid operations by tracking whether uCode is loaded.

0aef8ddc8b iwlwifi: add testmode command for rx forwarding
Added a testmode command which tells iwl_rx_dispatch
to send the RX both as a notification to nl80211 and
with the registered RX handlers.

This is used for monitoring RX from userspace while preserving
the regular flows in the driver.

4bd14dd5f7 iwlwifi: abstract out notification wait support
This will be sharable, but needs to live in the
op_mode as it is dependent on command processing.
Make a library out of the notification wait code.

Since I wrote all of the code originally and only
Intel employees changed it, we can also relicense
it to dual BSD/GPL.

e10a0533a9 iwlwifi: add wrappers for command sending
Add wrappers to send commands from the DVM
op-mode (which essentially consists of the
current driver). This will allow us to move
specific sanity checks there.

Also, this removes iwl_trans_send_cmd_pdu()
since that can now be taken care of in the
DVM-specific wrapper.

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.

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.

e19918855d iwlwifi: move ucode loading to op_mode
uCode loading belongs to the op_mode, as it
is dependent on various things there and the

dependent after all).

48a2d66f58 iwlwifi: don't pass iwl_rx_mem_buffer to upper layers
struct iwl_rx_mem_buffer implementation details
(DMA address, list pointers) that the upper
layers don't need. Introduce iwl_rx_cmd_buffer
that is passed upstream and only contains the
needed data (the page). Additionally, access
this data only via accessor functions, allowing
us to change the implementation in the future.
These accessors are rxb_addr() (as before) and
rxb_steal_page() to take ownership of the data.

65b94a4abf iwlwifi: pass response packet directly
When CMD_WANT_SKB is set for a (synchronous)
command, the response is passed back to the
caller which is then responsible for freeing
it. Make this more abstract with real API,
passing directly the response packet in the
new cmd.resp_pkt member and also introduce
iwl_free_resp() to free the pages -- this
way the upper layers don't have to directly
touch the page implementation.

NOTE: This breaks IDI -- the new code isn't reflected there yet!

6c55f5ed3a iwlwifi: testmode new indirect RW API
Replaced the old SRAM and periphery indirect access functions
with a unified indirect memory access functions. These include
new IWL_TM_CMDs for buffer read/write/dump which replace the
SRAM read/dump commands, but the API for IWL_TM_CMD_INDIRECT_REG
read/write will now not be supported (returns error).

This also handles writing to periphery registers in 1-3 bytes.

Requires the corresponding patch in the library for the API change.
