Johan Hedberg 5517893543 Bluetooth: Make bt_hci_driver instances link-time constants
Declaring these as const lets the linker generate more optimal code.
Some extra care is needed with hci_ecc.c since it was overwriting the
send callback. Now the choice of send() call is done directly in the
bt_send() function

Johan Hedberg 50678b03cb Bluetooth: Reuse HCI command buffers for the command response
Reduce the pressure on the common RX buffer pool by reusing HCI
command buffers also for the Command Status or Command Complete
response to them. This also implies removing the existing Kconfig
variable for the command buffer sizes since the size is also dependent
on maximum Command Complete event sizes. Instead, reuse the RX buffer
size also for HCI Command buffers.

If we are low on RX buffers and receive an LE Advertising Report or a
BR/EDR Inquiry response we should just discard this. If we don't
discard the event we increase the risk of deadlock where the RX
interrupt is enabled but bt_recv() is doing a synchronous HCI command
sending, i.e. waiting for a cmd_status/cmd_complete (which will never
come since the RX interrupt is disabled).

Lee Jones 7890290e81 Bluetooth: Add HCI SPI driver
This driver acts as a pass-through, taking raw HCI data, converting
it to SPI comms and vice versa.  It works in the same way as the
existing H:4 and H:5 drivers, only it uses SPI instead of UART.

In this first release, the only BLE board which has been tested is
the X-NUCLEO-IDB05A1:

  http://www.st.com/en/ecosystems/x-nucleo-idb05a1.html

Although the current supported SPI format works like the one below,
it should be trivial to adapt it to support other chips with a
different format.

SANITY CHECK = 0x02
SPI WRITE    = 0x0A
SPI READ     = 0x0B

Tx Format:

   [HOST] {SPI WRITE}     0x00          0x00  0x00  0x00  {HCI MESSAGE ...}
   [CHIP] {SANITY CHECK}  {FLASH SIZE}  0x00  0x00  0x00  {0xFF * MESSAGE LEN}

Rx Format:

   {IRQ LINE GOES HIGH}

   [HOST] {SPI READ}  0x00          0x00  0x00             0x00  {0xFF * BYTES TO READ}
   [CHIP] 0x02        {FLASH SIZE}  0x00  {BYTES TO READ}  0x00  {HCI MESSAGE ...}

Johan Hedberg 645f867444 Bluetooth: Take advantage of IS_ENABLED macro for BT_DBG
The new IS_ENABLED macro allows exposing conditionally enabled code
always to the compiler, even though it may not ultimately end up being
built. This is in particular useful for letting the compiler catch any
logging format string errors. Introduce a new BT_DBG_ENABLED macro
that c-files need to define before including <bluetooth/log.h> in
order to choose whether BT_DBG() logs are enabled or not.

When no Bluetooth logs are enabled the patch also modifies the log
macros to have the format strings checked with the help of the
__printf_like annotation and empty static inline functions.

So far the use of k_sem meant that there was no major benefit of
having more than 2 or 3 RX buffers since there was no queuing
mechanism. Instead of using k_sem, introduce a k_fifo and use that to
queue up incoming buffers. This way the RX buffer count can be
increased with measurable effects on throughput.

In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information

there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

Johan Hedberg c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

Johan Hedberg b64e0d4c51 Bluetooth: Kconfig: Remove redundant 'default n' declarations
All boolean options default to 'n' without the need to explicitly
state this. It's only the cases where we want 'default y' where we
need to state this.

Johan Hedberg c583a9f43b Bluetooth: Kconfig: Restructure for a more logical hierarchy
Restructure the Bluetooth options more logically.

- Both host and controller are now behind the same high level
  CONFIG_BLUETOOTH.

- Selecting controller support disables other HCI driver selection, so
  the controller isn't in the same list as HCI drivers any more.

- Under the top-level there's a "Custom stack" option, which when
  enabled opens up the option of choosing CONFIG_NBLE.

There are various other cleanups and simplifications in this patch as
well, since splitting these up would have been fairly tricky while
making sure all test cases still build.

Johan Hedberg d7f4fd74a9 Bluetooth: Use depends on SERIAL instead of selects
This suppresses warnings for platforms where SERIAL can't be provided.
All the platforms that these drivers are interesting for already
default to SERIAL=y.
