Bluetooth: Make UART draining logic consistent across drivers There's no need to drain twice if NRF51_PM is enabled, the draining shouldn't use rx_ready(), and it should happen after disabling interrupts. Also rename uart.h to util.h to avoid conflicts with include/uart.h and remove the left-over ISR prototype declaration.

/* util.h - Common helpers for Bluetooth drivers */
Bluetooth: Add HCI UART (H4) driver This patch adds a simple HCI UART (H4) driver that currently maps to the second UART in the system. The main intention is to use this together with qemu for accessing the Bluetooth controller available on the host OS side. The H4 HCI transport protocol is perhaps the simplest of the standard HCI transports. It consists of a single byte in the beginning of each packet which indicates the type of the packet: HCI event, HCI command, ACL data, or SCO data (which we don't use at the moment).

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.
