Decisions on compiler optimizations were done on the architecture level,
this does not scale and some SoCs will have different optimization levels
or compiler options needed. Moving this to the SoC makes it easy to optimize
differently when using the same CPU which we use to set the right optimization
now on the architecture level.
For IAMCU platforms, use the right architecture and tuning.

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.

Currently, if we disable I2C_DW through 'menuconfig', I2C_DW_0* and
I2C_DW_1* options are not disabled even if they depend on I2C_DW
option. This makes the menuconfig confusing and we end up with the
wrong config set in .config file:
...
CONFIG_I2C_DW is not set
CONFIG_I2C_DW_0=y
...
CONFIG_I2C_DW_1=y
...
This patch fixes this issue by surrounding the I2C_DW_0* and I2C_DW_1*
options with 'if I2C_DW'.

On SysV ABI, the NANO_ESF parameter is passed in via the stack.
For IAMCU, this is instead expected to be in EAX.
_ExcEnter is currently using EAX to stash the return address of
the calling stub while it does a stack switch. Change it to use ECX
for this purpose, and if we are running with IAMCU place the
parameter in EAX instead of pushing it.

driver based on RTC driver provided by QMSI BSP.
Some config options are independent of the driver implementation used,
so use a consistent name for them. In this case RTC Interrupt number and
Priority use the same config options for both the QMSI and DesignWare
drivers.
In order to enable this driver, the following options should be set:

CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_RTC=y

If we are not doing any dynamic interrupts or exceptions, we
can put the IDT in ROM and save a considerable amount of RAM,
up to 2K if the IDT is the default size of 256 entries.
The _interrupt_vectors_allocated table can also be put in ROM

We introduce a new Kconfig option to force the IDT to be in RAM
for situations where no dynamic IRQs are used, but ROM footprint
needs to be conserved.

Quark SE Lakemont core has a hardware bug where the LOAPIC does
not properly notify the IOAPIC to clear the IRR bit for level-
triggered interrupts.
This patch introduces a workaround where the vector ID of the
in-service interrupt is manually written to the IOAPIC_EOI
register, resulting in the bit being cleared.
Unfortunately, in the context where EOI happens it's very difficult
to identify which IRQ line is being serviced, so this is done
unconditionally for all interrupts vectors whether they are registered
in the IOAPIC RTE table or not.

We are interested in supporting some XIP x86 platforms which are
unable to fetch CPU instructions from system RAM. This requires
refactoring our dynamic IRQ/exc code which currently synthesizes
assembly language instructions to create IRQ stubs on-the-fly.
Instead, a new approach is taken. Given that the configuration at
build time specifies the number of required stubs, use this
to generate a build time a set of tiny stub functions which simply
push a 'stub id' and then call common dynamic interrupt code.
The handler function and handler argument is saved in a table keyed by
this stub id.
CONFIG_EOI_HANDLER_SUPPORTED removed, the code hasn't been conditionally
compiled for some time and in all cases we call _loapic_eoi() when
finished with an interrupt.
Some other out-of-date verbiage in comments related to supporting
non-APIC removed.
Previously, when dynamic exceptions were created a pointer would
be passed in by the caller reserving ram for the stub code. Since
this is no longer feasible, two new Kconfig options have been added.
CONFIG_NUM_DYNAMIC_EXC_STUBS and CONFIG_NUM_DYNAMIC_EXC_NO_ERR_STUBS
control how many stubs are created for exceptions that push
an error code, and no error code, respectively.
SW Interrupts are no longer triggered by "int <vector>" hard-coded
assembly instructions. Instead this is done by sending a self-directed
inter-processor interrupt from the LOAPIC, using a new API
loapic_int_vect_trigger(). In this way we get rid of dynamically
generated code in irq_test_common.h.
All interrupts call _loapic_eoi() when finished, since this is now
the right thing to do for all IRQs, including SW interrupts.
_irq_handler_set() for x86 no longer requires the old function pointer
to be supplied.

Removing many of the typedefs that are only used once to lessen the
checkpatch warning about creating new typedefs. A handful have been
behind as they would require a more invasive change to the code. It
has yet to be determined if this is a worthwhile endavour.

If PWM had been configured by some other application after the last
power cycle, it would appear to work fine. However, an application using
PWM loaded right after a power cycle would not work, since the configure
call was missing during boot.

This was only needed for the older 8259A style PICs which are no
longer supported.
Since we now just support APIC, we always just call loapic_eoi which
no longer requires an argument and informs the IOAPIC that the interrupt
is complete if necessary.

ioapic_irq_set() needs a vector number: all calls to it now use the
_IRQ_TO_INTERRUPT_VECTOR() macro as expected.
The previous change by which interrupt priorities are now honoured
correctly when connecting ISRs to IRQs statically also changed the way
the interrupt vectors are assigned.
Instead of computing them like this:
interrupt vector ID = IRQ + INT_VEC_IRQ0
They are now determined by a macro:
interrupt vector ID = _IRQ_TO_INTERRUPT_VECTOR(irq)

Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.
All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM. This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.
This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.
