There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.
All Raspberry Pi models 1-3 (based on bcm2835) have
Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25):
/* dma channel 11-14 share one irq */
This information is repeated in the driver code
(drivers/dma/bcm2835-dma.c +1344):
/*
* in case of channel >= 11
* use the 11th interrupt and that is shared
*/
In this patch channels 0--10 and 11--14 are handled separately.

This change moves the code that connects the SoC UART's to serial_hd's
to the machine.
It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.
This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.
This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.
I tested this using the images and commands from the previous
refactoring, and another test image for the ast1030:

To support multiple SoC's running simultaneously, we need a unique name for
each RAM region. DRAM is created by the machine, but SRAM is created by the
SoC, since in hardware it is part of the SoC's internals.
We need a way to uniquely identify each SRAM region though, for VM
migration. Since each of the SoC's CPU's has an index which identifies it
uniquely from other CPU's in the machine, we can use the index of any of the
CPU's in the SoC to uniquely identify differentiate the SRAM name from other
SoC SRAM's. In this change, I just elected to use the index of the first CPU
in each SoC.

This introduces a really basic PECI controller that responses to
commands by always setting the response code to success and then raising
an interrupt to indicate the command is done. This helps avoid getting
hit with constant errors if the driver continuously attempts to send a
command and keeps timing out.
The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC.
They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support
PECI 4.0, which includes more read/write buffer registers from 0x80 to
0xFC to support 64-byte mode.
This patch doesn't attempt to handle that, or to create a different
version of the controller for the different generations, since it's only
implementing functionality that is common to all generations.
The basic sequence of events is that the firmware will read and write to
various registers and then trigger a command by setting the FIRE bit in
the command register (similar to the I2C controller).
Then the firmware waits for an interrupt from the PECI controller,
expecting the interrupt status register to be filled in with info on
what happened. If the command was transmitted and received successfully,
then response codes from the host CPU will be found in the data buffer
registers.

Background:
AspeedMachineClass.uart_default specifies the serial console UART, which
usually corresponds to the "stdout-path" in the device tree.
The default value is UART5, since most boards use UART5 for this:
amc->uart_default = ASPEED_DEV_UART5;
Users can override AspeedMachineClass.uart_default in their board's machine
class init to specify something besides UART5. For example, for fuji-bmc:
amc->uart_default = ASPEED_DEV_UART1;
We only connect this one UART, of the 5 UART's on the AST2400 and AST2500
and the 13 UART's on the AST2600 and AST1030, to a serial device that QEMU
users can use. None of the other UART's are initialized, and the only way
to override this attribute is by creating a specialized board definition,
requiring QEMU source code changes and rebuilding.
The result of this is that if you want to get serial console output on a
board that uses UART3, you need to add a board definition. This was
encountered by Zev in OpenBMC. [1]
Changes:
This commit initializes all of the UART's present on each Aspeed chip with
serial devices and allows the QEMU user to connect as many or few as they
like to serial devices. For example, you can still run QEMU and just connect
stdout to the machine's default UART, without specifying any additional
serial devices:
qemu-system-arm -machine fuji-bmc \
-drive file=fuji.mtd,format=raw,if=mtd \
-nographic
However, if you don't want to add a special machine definition, you can now
manually configure UART1 to connect to stdout and get serial console output,
even if the machine's default is UART5:
qemu-system-arm -machine ast2600-evb \
-drive file=fuji.mtd,format=raw,if=mtd \
-serial null -serial mon:stdio -display none
In the example above, the first "-serial null" argument is connected to
UART5, and "-serial mon:stdio" is connected to UART1.
Another example: you can get serial console output from Wedge100, which uses
UART3, by reusing the palmetto AST2400 machine and rewiring the serial
device arguments:
qemu-system-arm -machine palmetto-bmc \
-drive file=wedge100.mtd,format=raw,if=mtd \
-serial null -serial null -serial null \
-serial mon:stdio -display none
There is a slight change in behavior introduced with this change: now, each
UART's memory-mapped IO region will have a serial device model connected to
it. Previously, all reads and writes to those regions would be ineffective
and return zero values, but now some values will be nonzero, even when the
user doesn't connect a serial device backend (like a socket, file, etc). For
example, the line status register might indicate that the transmit buffer is
empty now, whereas previously it might have always indicated it was full.

The traditional ptimer behaviour includes a collection of weird edge
case behaviours. In 2016 we improved the ptimer implementation to
fix these and generally make the behaviour more flexible, with
ptimers opting in to the new behaviour by passing an appropriate set
of policy flags to ptimer_init(). For backwards-compatibility, we
defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old
weird behaviour.
This turns out to be a poor choice of name, because people writing
new devices which use ptimers are misled into thinking that the
default is probably a sensible choice of flags, when in fact it is
almost always not what you want. Rename PTIMER_POLICY_DEFAULT to
PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that
new devices should not be using it.
The code-change part of this commit was produced by
sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT)

In the virt board with secure=on we put two nodes in the dtb
for flash devices: one for the secure-only flash, and one
for the non-secure flash. We get the reg properties for these
correct, but in the DT node name, which by convention includes
the base address of devices, we used the wrong address. Fix it.
Spotted by dtc, which will complain
Warning (unique_unit_address): /flash@0: duplicate unit-address (also used in node /secflash@0)
if you dump the dtb from QEMU with -machine dumpdtb=file.dtb
and then decompile it with dtc.

This adds code to instantiate the slightly extended ACPI root port
description in DSDT as per the CXL 2.0 specification.
Basically a cut and paste job from the i386/pc code.

As part of converting -boot to a property with a QAPI type, define
the struct and use it throughout QEMU to access boot configuration.
machine_boot_parse takes care of doing the QemuOpts->QAPI conversion by
hand, for now.

When CPU-to-NUMA association isn't explicitly provided by users,
the default one is given by mc->get_default_cpu_node_id(). However,
the CPU topology isn't fully considered in the default association
and this causes CPU topology broken warnings on booting Linux guest.
For example, the following warning messages are observed when the
Linux guest is booted with the following command lines.

BUG: arch topology borken

<the above error log repeats>
BUG: arch topology borken
the DIE domain not a subset of the NODE domain
With current implementation of mc->get_default_cpu_node_id(),
CPU#0 to CPU#5 are associated with NODE#0 to NODE#5 separately.
That's incorrect because CPU#0/1/2 should be associated with same
NUMA node because they're seated in same socket.
This fixes the issue by considering the socket ID when the default
CPU-to-NUMA association is provided in virt_possible_cpu_arch_ids().
With this applied, no more CPU topology broken warnings are seen
from the Linux guest. The 6 CPUs are associated with NODE#0/1, but
there are no CPUs associated with NODE#2/3/4/5.

Currently, the SMP configuration isn't considered when the CPU
topology is populated. In this case, it's impossible to provide
the default CPU-to-NUMA mapping or association based on the socket
ID of the given CPU.
This takes account of SMP configuration when the CPU topology
is populated. The die ID for the given CPU isn't assigned since
it's not supported on arm/virt machine. Besides, the used SMP
configuration in qtest/numa-test/aarch64_numa_cpu() is corrcted
to avoid testing failure

The sbsa-ref machine is continuously evolving. Some of the changes we
want to make in the near future, to align with real components (e.g.
the GIC-700), will break compatibility for existing firmware.
Introduce two new properties to the DT generated on machine generation:
- machine-version-major
To be incremented when a platform change makes the machine
incompatible with existing firmware.
- machine-version-minor
To be incremented when functionality is added to the machine
without causing incompatibility with existing firmware.
to be reset to 0 when machine-version-major is incremented.
This versioning scheme is *neither*:
- A QEMU versioned machine type; a given version of QEMU will emulate
a given version of the platform.
- A reflection of level of SBSA (now SystemReady SR) support provided.
The version will increment on guest-visible functional changes only,
akin to a revision ID register found on a physical platform.
These properties are both introduced with the value 0.
(Hence, a machine where the DT is lacking these nodes is equivalent
to version 0.0.)
