Bluetooth: Offload ECC calculations to task If TinyCrypt ECC is used for LE SC calculations need to be done in task to avoid hogging CPU from non-preemptible fiber. To keep upper layers of stack independent of crypto used (TinyCrypt or controller) this patch adds HCI ECC emulation. If ECC emulation is enabled it is always used regardless of ECC support being present in controller.

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.

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 Change-Id: Iac74f5ee9bee097bbb34c11bd13d1d886700f5cc Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
