To quote the author:
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.

U-Boot provides a verified-boot feature based around FIT, but there is
no standard way of implementing it for a board. At present the various
required pieces must be built up separately, to produce a working
implementation. In particular, there is no built-in support for selecting
A/B boot or recovery mode.
This series introduces VPL, a verified program loader phase for U-Boot.
Its purpose is to run the verified-boot process and decide which SPL
binary should be run. It is critical that this decision happens before
SPL runs, since SPL sets up SDRAM and we need to be able to update the
SDRAM-init code in the field.
Adding VPL into the boot flow provides a standard place to implement
verified boot. This series includes the phase itself, some useful Kconfig
options and a sandbox_vpl build for sandbox. No verfied-boot support is
provided in this series.
Most of the patches in this series are fixes and improvements to docs and
