mem_pdu_rx is not runtime resized meaning PDU_RX_SIZE_MIN is no longer
relevant.
Dynamic resizing was a left-over from the old bt controller.
Its size field was only ever set to PDU_RX_SIZE_MIN.
PDU_RX_SIZE_MIN only accounted for advertise PDUs.
So we remove size field from mem_pdu_rx.
However, the rest of the BT controller expects to be able to pull
RX_CNT-number of valid nodes from the pool at init/reset (rx_alloc)
time. This will fail unless we inflate the capacity by one.
To avoid inflation-by-one, mem_* would have to be rewritten to avoid

This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.
This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.
The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.

The bluetooth controller has been using the flag '-Ofast' to keep
within a real-time limit. There are two problems with this; firstly,
when a project should be optimized for size it is standard to use -O2,
not -Ofast.
Secondly, optimization flags have been deemed to be non-portable, so
instead of directly using "-Ofast" we should use the intent-macro
OPTIMIZE_FOR_SPEED_FLAG to ensure toolchain portability.
Testing has shown that we are still within the real-time limit when
changing from -Ofast to -O2. -Ofast is about 1us and 1% faster, but
increases the code size by 13kB (5% of the available flash on a
nRF51).
Since the slowdown is comparatively small compared to the code size
increase we have decided to use -O2 in place of -Ofast.
Other optimization combinations were also measured and their results
can be seen below:

Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.
There are at least three problems with the patch:
1. It's inconsistent with how Kconfig works in other projects, which
might confuse newcomers.
2. Due to oversights, earlier 'range' properties are still preferred,
as well as earlier 'default' properties on choices.
In addition to being inconsistent, this makes it impossible to
override 'range' properties and choice 'default' properties if the
base definition of the symbol/choice already has 'range'/'default'
properties.
I've seen errors caused by the inconsistency, and I suspect there
are more.
3. A fork of Kconfiglib that adds the patch needs to be maintained.
Get rid of the patch and go back to standard Kconfig behavior, as
follows:
1. Include the Kconfig.defconfig files first instead of last in
Kconfig.zephyr.
2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
last in arch/Kconfig.
3. Include arch/<arch>/soc/*/Kconfig first instead of last in
arch/<arch>/Kconfig.
4. Swap a few other 'source's to preserve behavior for some scattered
symbols with multiple definitions.
Swap 'source's in some no-op cases too, where it might match the
intent.
5. Reverse the defaults on symbol definitions that have more than one
default.
Skip defaults that are mutually exclusive, e.g. where each default
has an 'if <some board>' condition. They are already safe.
6. Remove the prefer-later-defaults patch from Kconfiglib.
Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions
As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).
This commit includes some default-related cleanups as well:
- Simplify some symbol definitions, e.g. where a default has 'if FOO'
when the symbol already has 'depends on FOO'.
- Remove some redundant 'default ""' for string symbols. This is the
implicit default.
Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).
Piggyback some fixes for style nits too, e.g. unindented help texts.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Remove some 'default ""' properties on string symbols too.
Also make definitions more consistent by converting some
config FOO
<type>
prompt "foo"
definitions to a shorter form:
config FOO
<type> "foo"
This shorthand works for int/hex/string symbols too, not just for bool
symbols.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:

The main purpose of recv_thread is to process incoming events from the
radio and also any buffered items waiting to be dispatched to the Host
and that are pending because of lack of Host buffers.
When an iteration of the recv_thread obtains a element from the radio it
needs to process it immediately, either sending it straight away to the
Host or appending it to the queue. This was not the case before this
patch, where the concurrency of a buffered packet with one coming from
the radio would cause the latter to be "dropped", causing missing
packets.

The assert is reproduced in bt shell by starting advertising

window 2.5ms), on nRF51x. If the overheads and/or a
advertiser event delayed the scheduling of scanner by over
2.5ms, then the preparation of scanner asserted.

The Bluetooth Specification allows for optional Controller to Host flow
control based on the same credit-based mechanism as the Host to
Controller one. This is particularly useful in 2-chip solutions where
the Host and the Controller are connected via a physical link (UART, SPI
or similar) where the Host is sometimes required to ask the Controller
to throttle its data traffic while still making sure that relevant
events get through the line.
This implementation is based on a simple queue of pending events and
data that is populated whenever the Controller detects that the Host is
out of buffers and then emptied whenever the Host notifies the
Controller that is ready to receive data again. Events relevant to the
connections are also queued to preserve the order of arrival.
At this point the Controller ignores the connection handle sent by the
Host and treats all connections equally, and it also queues events even
for connections that have no data pending in the queue. Both this items
can be improved if necessity arises.
Note that Number of Completed Packets will still flow freely from the
Controller to the Host regardless of the pending ACL data packets, which
might lead to inconsistencies in the sequential order of certain
operations that include bi-directional data transfer.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

tx/rx, taking into account predictive processing time
requirements in preparation to the event, like control
procedure handling and CPU execution speeds. Crystal
oscillator is retained between closely spaced consecutive

This feature maximizes radio utilization in an average role

reduced offset between preparation and radio event.
By disabling this feature, the controller will use a
constant offset between the preparation and radio event. The
controller will toggle crystal oscillator between two
closely spaced radio events leading to higher average
current due to increased number of crystal settling current
consumptions.

Controller asserted in preparation of a role event due to
the previous (same or another) role event preparation being
not complete.
Mayfly callee was disabled in the previous event due to the
preparation time being short and previous start running
(higher natural priority) before all previous preparation
mayfly completed. The previous start disabled mayfly to
avoid Radio ISR latencies.
The current role event that asserted, preempted the
previous role (observer role with continuous scanning
window) which runs until preemption to maximise the Radio
h/w use (observer scanning until next interval). The
previous preparation mayfly is still disabled when the
current role preparation tries to use same mayfly instance
which should be free for a new enqueue.
This commit updates mayfly implementation so that mayfly
callee is disabled only after all enqueued mayfly instances
are run to completion.

In order that host can continue a connection event by
enqueuing packets, the number of completed packets event
needs to be generated as soon it arrives on air. Hence, the
Controller now calls the radio_event_callback on every radio
Rx complete ISR.
The callback executes at the Radio ISR priority, take care
to only do as little as necessary in the callback, say, just
a semaphore give to wake up the hci_driver's thread.

This commit introduces a very light-weight and lock-less
scheduling of the Controller's deferred function calls
called the Mayfly.
Earlier work implementation used in the Controller had an
O(n) to schedule a function in a linked list that used IRQ
lock during modification of the linked list in the
Controller's ISR executions.
Mayfly is a compile time configurable matrix of queues
where an execution context-safe queue exists between two
execution context, one being the caller and the second
being the callee. Callee(s) are run in a software interrupt
but can also be run in an OS thread.
There are minor clean ups too in this commit related to
folder structure.

On CPUs like nRF51 which run at 16MHz, certain BLE control
procedure PDU processing take more CPU time than permitted
inside tIFS (150us). Current implementation of Data Length
Update procedure does not span over multiple connection
interval (unlike Encryption Setup, which is another control
procedure processing that would consume more CPU time)
hence taking more CPU time inside tIFS on nRF51.
During the radio ISR, the active clock and packet timer are
active and it is used to profile the CPU time taken which
is used to decide on whether there is sufficient time in
the current radio event to process the control packet.
This commit also fixes a potential bug that would cause
disconnection due to MIC failure on encrypted connections
that performed Data Length Update. Controller used to NACK
the request/response PDU if it was not in a state to resize
the receive buffers but did not reset the CCM counter. This
is now fixed by the change done to NACK control PDU based
on available CPU time in radio ISR.
