Ulf Magnusson a84ded74ea dts: Replace status = "ok" with status = "okay"
The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.

The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.

The replacement was done with

    git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'

Charles E. Youse c5aa535c98 boards/up_squared: soc/apollo_lake: devicetree default to status="ok"
Since Kconfig is responsible for enabling/disabling devices at build,
the devices in dt are defaulted to status="ok" to keep the output in
generated_dts_board.conf the same across configurations and simplify
the board-level dts files.

Previous the register size was 1M, technically the there are only a
small handful of registers defined in the IOAPIC, so shrinking the size
to 4k, so its as most one page large.

Kumar Gala e7cc51094a dts: x86: Move ioapic node out of cpu container
The IOAPIC node shouldn't have been in the cpu container, especially
since the cpu container does:

	#address-cells = <1>;
	#size-cells = <0>;

So the reg field of the IOAPIC would be treated as 2 registers instead
of a register and size.  Move IOAPIC node out of the CPU node fixes this
issue.

to the SoC-level. Also turn on auto IRQ detection as these are PCI-

Charles E. Youse 6fc655351c drivers/gpio/gpio_intel_apl: remove dependency on shared interrupts
The GPIO driver for the Intel Apollo Lake has so many pins it has to
export ten devices to shoehorn its one device into the GPIO API. The
current implementation uses the shared IRQ driver because these
pseudodevices all share one IRQ. However, since the GPIO driver is
aware of all the possible interrupt sources, it's smaller and faster
(and not even messy) to handle it internally, so this patch eliminates
the dependency on the shared IRQ driver.

Charles E. Youse e039053546 uart/ns16550, drivers/pcie: add PCI(e) support
A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.

The NS16550 UART driver is modified to use pcie.

pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.

This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.

Deficiencies:

64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.

The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.
