Each chip family has a different block size and calculates the total
number of HW blocks differently, with respect to alignment.

The number of spare Tx blocks must be changed when the GEM cipher is
engaged. Track set_key() operations to see if this is the case and
change the Tx HW spare block count accordingly. Set the number of spare
blocks for each operating mode from the low level driver.

Each chip family can have a different amount of Tx descriptors. These

This storage is allocated in wlcore_alloc_hw and freed in free_hw. The
size of the storage is determined by the low-level driver.

ELP is a very complicated process in the firmware.  Due to its
complexity, in some early firmware revisions, the ELP feature is
disabled.  To support this cases, this patch adds a quirk that
disables ELP mode.

When ELP is not supported, do not attempt to enter ELP when requested by
the driver.

We were reading the even mailbox address three times, which was
completely unnecessary and complicated things regarding partition
selection.  Remove the unnecessry reads and set the address for
mailbox 1 and 2 after the first read.

Instead of checking the chip ID directly in the wlcore code to decide
whether to use the new or the old NVS format, we now use a quirk that
should be set by the low level driver to say that it needs to use the
old format.

Different chips may use different bits in the interrupt trigger
register.  Add operations to handle these differences.

Different chip families have the factory MAC address written in
different places.  Add a new hardware operation to read the MAC
address, if available.

The top registers initialization is very specific to the actual
hardware used, even the way in which we read from and write to the top
registers varies from chip to chip.  This patch moves all top
registers initialization to wl12xx.  Also add a boot op for the wlcore
module to call at the right time and a few callbacks with the common
called to be called from the lower drivers boot operations.

The PG version depends on the actual hardware.  This commit moves the
code used to read the PG version to the lower driver, by adding the
get_pg_ver hardware operation.

Move the code that identifies the chip ID and selects the appropriate
firmware to an operation implemented by the lower driver.  Also move
the quirks definitions into wlcore.h and rename to WLCORE_QUIRK_*.

Add register tables support in wlcore, add some new IO functions to
read and write to chip-specific register and data addresses.  Move
some common register values from wl12xx to wlcore and add the
registers table to wl12xx.

Add partition tables to wlcore, move and reorganize partition setting

In order to add chip-specific operations and prepare for future
elements that need to be set by the lower driver, move the wl1271

We need to set some parameters (eg. partition and register tables)
during probe of the lower driver, so split the probe function, leaving
most of it in wlcore, but moving the hw struct allocation to the lower
driver.

Rename the wl12xx driver directory to wlcore as an initial step

rename the directory first to keep git blame happy.

Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti
