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.

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

options and a sandbox_vpl build for sandbox. No verfied-boot support is

sandbox: Add a build for VPL

Add an initial VPL build for sandbox. This includes the flow:

   TPL (with of-platdata) -> VPL -> SPL -> U-Boot

To run it:

   ./tpl/u-boot-tpl -D

The -D is needed to get the default device tree, which includes the serial
console info.

Add a Makefile check for OF_HOSTFILE which is the option that enables
devicetree control on sandbox.

arm: mvebu: turris_omnia: Add support for USB3.0 mode in WWAN MiniPCIe slot

PCIe Mini CEM 2.1 spec added support for USB3.0 mode on MiniPCIe cards.
USB3.0 and PCIe share same pins and only one function can be active at the
same time. PCIe Mini CEM 2.1 spec says that determining function is
platform specific and spec does not define any dedicated pin which could
say if card is USB3.0-based or PCIe-based.

Implement this platform specific decision (USB3.0 vs PCIe) for WWAN
MiniPCIe slot on Turris Omnia via U-Boot env variable "omnia_wwan_slot",
similarly like is implemented forced mode for MiniPCIe/mSATA slot via
"omnia_msata_slot" env variable. Value "usb3" for "omnia_wwan_slot" would
mean to set USB3.0 mode and value "pcie" original PCIe mode.

A385 SoC on Turris Omnia has configurable fifth SerDes line (exported to
MiniPCIe WWAN slot with SIM card) either to USB3.0 or PCIe functionality,
so implementation of this new PCIe Mini CEM 2.1 feature is simple, by just
configuring SerDes to USB 3.0 mode.

Other twos MiniPCIe slots on Turris Omnia do not have this new
functionality as their SerDes lines cannot be switched to USB3.0
functionality.

Note that A385 SoC does not have too many USB3.0 blocks, so activating
USB3.0 in MiniPCIe cause that one external USB3.0 USB-A port would loose
USB3.0 functionality and would be downgraded just to USB2.0.

By default this MiniPCIe WWAN slot is in PCIe mode, like before.

To set this MiniPCIe WWAN slot to USB3.0 mode, call U-Boot commands:

  => setenv omnia_wwan_slot usb3
  => saveenv
  => reset

Basic ASAN was easy to turn on, but integrating with dlmalloc was
messier and fairly intrusive. Even when I had it working, there was only
