The '#if XIP' in the DTS file never worked properly,
causing the QEMU build to think it has much more RAM
then it actually has. If RAM overflowed, this would not
be caught by the build, instead there would be strange
crashes when the data copy takes place.
The QEMU targets themselves are not XIP, everything
is actually RAM, but the first 4 megabytes are
considered to be a memory-mapped flash region. This
is done to ensure that the XIP data copying infrastructure
doesn't bit-rot on x86. We are at the point where
a lot of things depend on this, so just select it in
the board Kconfig instead of enabling in the
defconfigs.

A new function pcie_irq_enable() is added to be used in lieu of
irq_enable() when the target device is PCI(e)-attached. The function
attempts to use MSI, when configured in the kernel and supported by
the endpoint; failing that, it will verify that IRQ requested is in
fact routed to the device by the boot firmware before enabling it.
The NS16550 UART driver is updated to use pcie_irq_enable().
The PCI(e) shell is extended to dump information about wired IRQs.
The up_squared devicetree is fixed (reverted?) to IRQ5 for UART1.
The galileo enables MSI by default.

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.

Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all". This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.
This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)

The build_grub.sh script cherry-picks 3 commits from the master branch
of grub because more recent build tools fail to build the latest stable
release (which is 2.02). This solves the problem on Fedora 29 for
example, but is not sufficient for Clear Linux.
This patch modifies the build_grub.sh script to use
grub-2.02-285-g5bc41db75 (latest from master as of 13 of March 2019).
That version compiles 'out-of-the-box' in the latest Ubuntu, Fedora and
Clear Linux.
There are additional tools required on the host system and the
documentation has been updated accordingly.

However, the QEMU boards all derive from the generic IA32

to disable these mitigations for this target since the
IAMCU compiler doesn't even recognize instructions like

Most of these are from source'ing a file within an 'if PINMUX', and then
adding another 'depends on PINMUX' within it.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.
