Move the OrangePi tests from tests/avocado/boot_linux_console.py into
a new file dedicated for OrangePi tests in the functional framework
and update the hash sums of the assets to sha256 along the way.
For the buildroot image and the Armbian image, we've got to switch to
a newer version since the old images have been removed from the server,
and the NetBSD image has been moved to the archive, so we need to update
this URL as well.

Commit e779e5c05a ("hw/pci-bridge: Add a Kconfig switch for the
normal PCI bridge") added a config switch for the pci-bridge, so
that the device is not included in the s390x target anymore (since
the pci-bridge is not really useful on s390x).
However, it seems like libvirt is still adding pci-bridge devices
automatically to the guests' XML definitions (when adding a PCI
device to a non-zero PCI bus), so these guests are now broken due
to the missing pci-bridge in the QEMU binary.
To avoid disruption of the users, let's re-enable the pci-bridge
device on s390x for the time being.

Commit e554e45b44 ("aspeed: Tune eMMC device properties to reflect
HW strapping") added support to boot from an eMMC device by setting
the boot properties of the eMMC device. This change made the
assumption that the device always has boot areas.
However, if the machine boots from the flash device (or -kernel) and
uses an eMMC device without boot areas, support would be broken. This
impacts the ast2600-evb machine which can choose to boot from flash or
eMMC using the "boot-emmc" machine option.
To provide some flexibility for Aspeed machine users to use different
flavors of eMMC devices (with or without boot areas), do not set the
eMMC device boot properties when the machine is not configured to boot
from eMMC. However, this approach makes another assumption about eMMC
devices, namely that eMMC devices from which the machine does not boot
do not have boot areas.
A preferable alternative would be to add support for user creatable
eMMC devices and define the device boot properties on the QEMU command
line :
-blockdev node-name=emmc0,driver=file,filename=mmc-ast2600-evb.raw \
-device emmc,bus=sdhci-bus.2,drive=emmc0,boot-partition-size=1048576,boot-config=8
This is a global change requiring more thinking. Nevertheless, in the
case of the ast2600-evb machine booting from an eMMC device and when
default devices are created, the proposed change still makes sense
since the device is required to have boot areas.

When calculating the index into the GIC's GPIO array for per-CPU
interrupts, we have to start with the number of SPIs. The code
currently hard-codes this to 'NUM_IRQS = 256'. However the number of
SPIs is set separately and implicitly by the value of
AST2700_MAX_IRQ, which is the number of SPIs plus 32 (since it is
what we set the GIC num-irq property to).
Define AST2700_MAX_IRQ as the total number of SPIs; this brings
AST2700 into line with AST2600, which defines AST2600_MAX_IRQ as the
number of SPIs not including the 32 internal interrupts. We can then
use AST2700_MAX_IRQ instead of the hardcoded 256.

Use the private peripheral interrupt definitions from bsa.h instead
of defining them locally.
Note that bsa.h defines these values as INTID values, which are all
16 greater than the PPI values that we were previously using. So we
refactor the code to use INTID-based values to match that.
This is the same thing we did in commit d40ab068c0 for sbsa-ref.
It removes the "same constant, different values" confusion where this
board code and bsa.h both define an ARCH_GIC_MAINT_IRQ, and allows us
to use symbolic names for the timer interrupt IDs.

The sd_bootpart_offset() function calculates the *runtime* offset which
changes as the guest switches between accessing the main user data area
and the boot partitions by writing to the EXT_CSD_PART_CONFIG_ACC_MASK
bits, so it shouldn't be used to calculate the main user data area size.
Instead, subtract the boot_part_size directly (twice, as there are two
identical boot partitions defined by the eMMC spec).

It's been an amazing experience working on PowerNV systems all these
years. Now it's time for IBM to take the lead on the QEMU machine and
shape its future. I'm stepping back as the maintainer of PowerNV.

PHYP uses 8-byte writes to the 2nd doubleword of the OS context
line when dispatching an OS level virtual processor. This
support was not used by OPAL/Linux and so was never added.
Without this support, the XIVE code doesn't notice that a new
context is being pushed and fails to check for unpresented
pending interrupts for that context.

Current code was updating the PIPR inside the xive_tctx_accept() function
instead of the xive_tctx_set_cppr function, which is where the HW would
have it updated.
Moved the update to the xive_tctx_set_cppr function which required
additional support for pool interrupts.

Hypervisor "pool" targets do not get their own interrupt line and instead
must share an interrupt line with the hypervisor "physical" targets.
This also means that the pool ring must use some of the registers from the
physical ring in the TIMA. Specifically, the NSR, PIPR and CPPR registers:
NSR = Notification Source Register
PIPR = Post Interrupt Priority Register
CPPR = Current Processor Priority Register
The NSR specifies that there is an active interrupt. The CPPR
specifies the priority of the context and the PIPR specifies the
priority of the interrupt. For an interrupt to be presented to
a context, the priority of the interrupt must be higher than the
priority of the context it is interrupting (value must be lower).
The existing code was not aware of the sharing of these registers.
This commit adds that support.

Adds support for single byte writes to offset 0xC38 of the TIMA address
space. When this offset is written to, the hardware disables the thread
context and copies the current state information to the odd cache line of
the pair specified by the NVT structure indexed by the THREAD CAM entry.
Note that this operation is almost identical to what we are already doing
for the "Pull OS Context to Odd Thread Reporting Line" operation except
that it also invalidates the Pool and Thread Contexts.

Adds support for single byte read of offset 0x838 of the TIMA address
space. According to the XIVE2 Specification, this causes the hardware
to atomically:
1. Read the number of bytes requested (lbz or lhz are supported).
2. Reset the valid bit of the thread context.
3. Return the number of bytes requested in step 1 to a register.

Currently any device tree passed with -dtb option in QEMU, was ignored
by the PowerNV code.
Read and pass the passed -dtb to the kernel, thus enabling easier
debugging with custom DTBs.
The existing behaviour when -dtb is 'not' passed, is preserved as-is.
But when a '-dtb' is passed, it completely overrides any dtb nodes or
changes QEMU might have done, such as '-append' arguments to the kernel
(which are mentioned in /chosen/bootargs in the dtb), hence add warning
when -dtb is being used
