2b441732ff interrupt_controller: gic: Support multiple GIC versions
The current GIC driver implementation only supports the GIC-400, which
implements the GICv2 interface.

This commit refactors the GIC driver to support multiple GIC versions
and adds GICv1 interface support (GICv1 and GICv2 interfaces are very
similar).

11d0f0a294 drivers: interrupt_controller: Refactor GIC configurations
The current GIC configuration scheme is designed to support only one
specific type and version of GIC (i.e. GIC-400 that implements the
GICv2 interface).

This commit adds a set of GIC version configuration symbols that can
be selected by the SoC configuration to specify which version of GIC
interface is implemented in the SoC.

4ada2f65d2 drivers/interrupt_controller: Renaming s1000 to cavs
If it is such a thing (a CAVT intc), it will not be targeting Intel
s1000 SoC only. UP squarde ADSP use the same intc. So renaming it to
CAVS. Though CAVS name might be wrong (CAVS being an overall
architecture name, and not an IP block specification).

Reducing the amount of lines by using if/endif as well.

7baf3f74a9 interrupt_controller: gic: Support PPIs
The GIC-400 driver currently only supports SPIs because the (32) offset
for the INTIDs is hard-coded in the driver. At the driver level there is
no really difference between PPIs and SPIs so we can easily extend the
driver to support PPIs as well.

This is useful if we want to add support for the ARM Generic Timers that
use INTIDs in the PPI range.

SPI interrupts are in the range [0-987]. PPI interrupts are in the range
[0-15].

This commit adds interrupt 'type' cell to the GIC device tree binding
and changes the 'irq' cell to use interrupt type-specific index, rather
than a linear IRQ number.

The 'type'+'irq (index)' combo is automatically fixed up into a linear
IRQ number by the scripts/dts/gen_defines.py script.

87e917a925 kconfig: Remove redundant 'default n' and 'prompt' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Also replace some

    config
    	prompt "foo"
    	bool/int

with the more common shorthand

    config
    	bool/int "foo"

005aff7743 interrupt_controller: ioapic_intr: revert CPU target change
Commit 5a9a33b0cf changes interrupt
destination in an attempt to broadcast interrupts. However, this
change causes interrupts to stop working on the UP Squared board
in non-SMP configuration. According to QEMU source code,
physical destination address 0xFF000000 is a special case where
it broadcasts the interrupts. However, none of the IOAPIC
documentation (that I can find) describes this behavior. So,
revert that commit.

975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

a981f51fe6 arch/x86: drivers/loapic_intr.c: move local APIC initialization
In the general case, the local APIC can't be treated as a normal device
with a single boot-time initialization - on SMP systems, each CPU must
initialize its own. Hence the initialization proper is separated from
the device-driver initialization, and said initialization is called
from the early startup-assembly code when appropriate.
