[PATCH v3 00/18] virtio: pci: Add and fix consistency checks

[Andrew Scull <ascull@google.com>]

The virtio PCI drivers forgo a number of consistency checks,
particularly around pointer validation and bounds checking. This series
focuses on the modern driver to add those checks.

The start of the series adds and fixes some basic bounds checks. Later
patches ensure PCI addresses fall within the expected regions rather
than any arbitrary address. This is acheived by introducing range
parameters to a few of the dm_pci_* functions that allow the ranges to
be checked.

The series also adds a few new configs to allow parts of virtio and PCI
to be disabled where the features may be unused and the current
implementations don't have the needed consistencty checks.

Changelog:
v2:
 - Refactor dm_pci_* functions, not adding new ones
 - Reorder patches per request in v1
v3:
 - Use CI to test more targets
 - Move EA config patch to end for dropping if needed
