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.

Andrew Boie e98ac235e6 x86: declare internal API for interrupt controllers
Originally, x86 just supported APIC. Then later support
for the Mint Valley Interrupt Controller was added. This
controller is mostly similar to the APIC with some differences,
but was integrated in a somewhat hacked-up fashion.

Now we define irq_controller.h, which is a layer of abstraction
between the core arch code and the interrupt controller
implementation.

Contents of the API:

- Controllers with a fixed irq-to-vector mapping define
_IRQ_CONTROLLER_VECTOR_MAPPING(irq) to obtain a compile-time
map between the two.

- _irq_controller_program() notifies the interrupt controller
what vector will be used for a particular IRQ along with triggering
flags

- _irq_controller_isr_vector_get() reports the vector number of
the IRQ currently being serviced

- In assembly language domain, _irq_controller_eoi implements
EOI handling.

- Since triggering options can vary, some common defines for
triggering IRQ_TRIGGER_EDGE, IRQ_TRIGGER_LEVEL, IRQ_POLARITY_HIGH,
IRQ_POLARITY_LOW introduced.

Specific changes made:

- New Kconfig X86_FIXED_IRQ_MAPPING for those interrupt controllers
that have a fixed relationship between IRQ lines and IDT vectors.

- MVIC driver rewritten per the HAS instead of the tortuous methods
used to get it to behave like LOAPIC. We are no longer writing values
to reserved registers. Additional assertions added.

- Some cleanup in the loapic_timer driver to make the MVIC differences
clearer.

- Unused APIs removed, or folded into calling code when used just once.

- MVIC doesn't bother to write a -1 to the intList priority field since
it gets ignored anyway

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

The change in API means that device drivers and sample

by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

Dmitriy Korovkin 660878e4e2 irq_connect for x86 uses static stub array
In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.

Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.

Modify tests for unified interrupt register API

Tests that deal with interrupts are modified to work
with the new interrupt registration API.

Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects

Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.

Dmitriy Korovkin 6dd108a263 IRQ_CONNECT_STATIC implementation for x86 platform
In order to simplify x86 interrupt stub creation, each interrupt
controller implements an interrupt stub definition macro.

Add IRQ_CONNECT_STATIC() for static interrupt registration, and
construct the interrupt stubs name from device and interrupt
handler names.

Add IRQ_CONFIG() macro for the interrupt controller configuration.
On x86 platform it programs APIC to associate an IRQ number with
the interupt vector.

Add HPET_TIMER0_INT_PRI parameter to Quark platform header to
make it build correctly.
