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. Jira: ZEP-1457 Change-Id: I6131a1d4ee0e58f5b938300c2d2fc77d2e69572c Signed-off-by: David B.

* Configure a static interrupt.

|

* All arguments must be computable by the compiler at build time.
|
|
*
|
|
* Internally this function does a few things:
|
|
*
|
|
* 1. The enum statement has no effect but forces the compiler to only
|
|
* accept constant values for the irq_p parameter, very important as the
|
|
* numerical IRQ line is used to create a named section.
|
|
*
|
|
* 2. An instance of _IsrTableEntry is created containing the ISR and its
|
|
* parameter. If you look at how _sw_isr_table is created, each entry in the
|
|
* array is in its own section named by the IRQ line number. What we are doing
|
|
* here is to override one of the default entries (which points to the
|
|
* spurious IRQ handler) with what was supplied here.
|
|
*
|
|
* 3. The priority level for the interrupt is configured by a call to
|
|
* _irq_priority_set()
|
|
*
|
|
* @param irq_p IRQ line number
|
|
* @param priority_p Interrupt priority, in range 0-13
|
|
* @param isr_p Interrupt service routine
|
|
* @param isr_param_p ISR parameter
|
|
* @param flags_p IRQ options (ignored for now)

*
|
|
* @return The vector assigned to this interrupt
