Vinayak Chettimada 2de3cc95be Bluetooth: controller: Move nRF5 specific debug pins to hal/nrf5
Move the nRF5 specific GPIO debug pin macro definitions to
hal/nrf5/debug.h.

The Controller's hal folder contains prototypes and
hal/<soc> shall contain SoC specific implementation to
realize a software-based Link Layer.

Vinayak Chettimada 0efd38885a Bluetooth: controller: Cleanup makefiles
Cleanup controller's root makefile and add folder level
makefile to have better control over dependencies.

Also explicitly include folder paths in c files to clearly
depict the dependencies.

Move the PDU related size definitions out of radio.h and
place it in pdu.h. This will remove hci's dependency on
radio.h.

Johan Hedberg 6cb853fc04 Bluetooth: Controller: Introduce big-endian variant for ECB
There are some use cases where all parameters are in big-endian. To
avoid excessive byte order reversals introduce a native big-endian
API.

Carles Cufi 727987276e Bluetooth: controller: Use direct ISRs
The new hard real-time (direct) interrupt support in the kernel allows
ISRs to be run directly with no significant latency overhead.

Use this new mechanism to improve the latency of the 3 critical
interrupts in the controller: radio, RTC0 and SWI4.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Vinayak Chettimada d5d473b0f8 Bluetooth: Controller: replace work with mayfly
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.

Vinayak Chettimada 6de7a808af Bluetooth: Controller: ctrl pdu processing based on available CPU time
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.

Carles Cufi f7d313b154 Bluetooth: Controller: Add ASSERT info dump on HCI builds
When building Zephyr in the controller-only configuration,
assertions that happen in the Link Layer code are not visible
to the Host which is running on another HCI and connected via
UART or USB to it. This patch allows the Controller code
to output the assertion line number when in such a configuration,
allowing the Host to view the event to help debugging.

The event format used is temporary and will be replaced by a
standardized Vendor Specific specification to come at a later
time.
