Add a minimal PCI test device designed to exercise IOMMU translation
(such as ARM SMMUv3) without requiring guest firmware or OS. The device
provides MMIO registers to configure and trigger DMA operations with
controllable attributes (security state, address space), enabling
deterministic IOMMU testing.
Key features:
- Bare-metal IOMMU testing via simple MMIO interface
- Configurable DMA attributes for security states and address spaces
- Write-then-read verification pattern with automatic result checking
The device performs a deterministic DMA test pattern: write a known
value (0x12345678) to a configured GVA, read it back, and verify data
integrity. Results are reported through a dedicated result register,
eliminating the need for complex interrupt handling or driver
infrastructure in tests.
This is purely a test device and not intended for production use or
machine realism. It complements existing test infrastructure like
pci-testdev but focuses specifically on IOMMU translation path
validation.

Move register definitions, command enums, and Stream Table Entry (STE) /
Context Descriptor (CD) structure definitions from the internal header
hw/arm/smmuv3-internal.h to a new common header
include/hw/arm/smmuv3-common.h.
This allows other components, such as generic SMMUv3 tests or test devices,
to utilize these definitions without including the specific SMMUv3 device
internal state.

Commit 369c1ba2b changed the wrong conditional "#if defined(__i386__)" to
"#if defined(TARGET_I386)".
However, TARGET_I386 is defined for target x86_64 also.
This commit fixes it by identifying correctly 32 bits target.

Commit 2ff8c9a298 removed support for 32-bit PPC hosts from the build
system. Unfortunately, the patch also removed the 32-bit PPC target for
containerized tests, which leads to an error when trying to run tests,
e.g., with "make check-tcg":
"make[1]: *** No rule to make target 'docker-image-debian-ppc-cross',
needed by 'build-tcg-tests-ppc-linux-user'. Stop."
This patch adds the PPC target back for containerized tests.

pc-bios/optionrom/Makefile uses $(PYTHON) for running a Python script,
but this variable is never initialized here. So the script gets run
via its shebang line - which fails if the "python3" binary is not

to the config.mak file of the optionroms.

This reverts commit fccb744f41.
This commit introduced dependency of linux-user on qemu-sockets.c.
The latter includes handling of various socket types, while gdbstub
only needs unix sockets. Including different kinds of sockets
makes it more problematic to build linux-user statically.
The original issue - the need to unlink unix socket before binding -
will be addressed in the next change.
