Steven Lee 356b230ed1 aspeed/soc : Add AST1030 support
The embedded core of AST1030 SoC is ARM Coretex M4.
It is hard to be integrated in the common Aspeed Soc framework.
We introduce a new ast1030 class with instance_init and realize
handlers.

Alistair Francis d24a7bc24e hw/core: Move the ARM sysbus-fdt to core
The ARM virt machine currently uses sysbus-fdt to create device tree
entries for dynamically created MMIO devices.

The RISC-V virt machine can also benefit from this, so move the code to
the core directory.

Jean-Philippe Brucker ced716942a hw/arm/smmuv3: Cache event fault record
The Record bit in the Context Descriptor tells the SMMU to report fault
events to the event queue. Since we don't cache the Record bit at the
moment, access faults from a cached Context Descriptor are never
reported. Store the Record bit in the cached SMMUTransCfg.

Peter Maydell 7cf3f8d243 hw/arm/virt: Support TCG GICv4
Add support for the TCG GICv4 to the virt board. For the board,
the GICv4 is very similar to the GICv3, with the only difference
being the size of the redistributor frame. The changes here are thus:
 * calculating virt_redist_capacity correctly for GICv4
 * changing various places which were "if GICv3" to be "if not GICv2"
 * the commandline option handling

Note that using GICv4 reduces the maximum possible number of CPUs on
the virt board from 512 to 317, because we can now only fit half as
many redistributors into the redistributor regions we have defined.

Peter Maydell f31985a77a hw/arm/virt: Abstract out calculation of redistributor region capacity
In several places in virt.c we calculate the number of redistributors that
fit in a region of our memory map, which is the size of the region
divided by the size of a single redistributor frame. For GICv4, the
redistributor frame is a different size from that for GICv3. Abstract
out the calculation of redistributor region capacity so that we have
one place we need to change to handle GICv4 rather than several.

Peter Maydell f37fc537fc hw/arm/exynos4210: Drop Exynos4210Irq struct
The only time we use the int_combiner_irq[] and ext_combiner_irq[]
arrays in the Exynos4210Irq struct is during realize of the SoC -- we
initialize them with the input IRQs of the combiner devices, and then
connect those to outputs of other devices in
exynos4210_init_board_irqs().  Now that the combiner objects are
easily accessible as s->int_combiner and s->ext_combiner we can make
the connections directly from one device to the other without going
via these arrays.

Since these are the only two remaining elements of Exynos4210Irq,
we can remove that struct entirely.

Peter Maydell 76621953c9 hw/arm/exynos4210: Fold combiner splits into exynos4210_init_board_irqs()
At this point, the function exynos4210_init_board_irqs() splits input
IRQ lines to connect them to the input combiner, output combiner and
external GIC.  The function exynos4210_combiner_get_gpioin() splits
some of the combiner input lines further to connect them to multiple
different inputs on the combiner.

Because (unlike qemu_irq_split()) the TYPE_SPLIT_IRQ device has a
configurable number of outputs, we can do all this in one place, by
making exynos4210_init_board_irqs() add extra outputs to the splitter
device when it must be connected to more than one input on each
combiner.

We do this with a new data structure, the combinermap, which is an
array each of whose elements is a list of the interrupt IDs on the
combiner which must be tied together.  As we loop through each
interrupt ID, if we find that it is the first one in one of these
lists, we configure the splitter device with eonugh extra outputs and
wire them up to the other interrupt IDs in the list.

Conveniently, for all the cases where this is necessary, the
lowest-numbered interrupt ID in each group is in the range of the
external combiner, so we only need to code for this in the first of
the two loops in exynos4210_init_board_irqs().

The old code in exynos4210_combiner_get_gpioin() which is being
deleted here had several problems which don't exist in the new code
in its handling of the multi-core timer interrupts:
 (1) the case labels specified bits 4 ... 8, but bit '8' doesn't
     exist; these should have been 4 ... 7
 (2) it used the input irq[EXYNOS4210_COMBINER_GET_IRQ_NUM(1, bit + 4)]
     multiple times as the input of several different splitters,
     which isn't allowed
 (3) in an apparent cut-and-paste error, the cases for all the
     multi-core timer inputs used "bit + 4" even though the
     bit range for the case was (intended to be) 4 ... 7, which
     meant it was looking at non-existent bits 8 ... 11.
None of these exist in the new code.

Peter Maydell 76124b4cb2 hw/arm/exynos4210: Don't connect multiple lines to external GIC inputs
The combiner_grp_to_gic_id[] array includes the EXT_GIC_ID_MCT_G0
and EXT_GIC_ID_MCT_G1 multiple times. This means that we will
connect multiple IRQs up to the same external GIC input, which
is not permitted. We do the same thing in the code in
exynos4210_init_board_irqs() because the conditionals selecting
an irq_id in the first loop match multiple interrupt IDs.

Overall we do this for interrupt IDs
(1, 4), (12, 4), (35, 4), (51, 4), (53, 4) for EXT_GIC_ID_MCT_G0
and
(1, 5), (12, 5), (35, 5), (51, 5), (53, 5) for EXT_GIC_ID_MCT_G1

These correspond to the cases for the multi-core timer that we are
wiring up to multiple inputs on the combiner in
exynos4210_combiner_get_gpioin().  That code already deals with all
these interrupt IDs being the same input source, so we don't need to
connect the external GIC interrupt for any of them except the first
(1, 4) and (1, 5). Remove the array entries and conditionals which
were incorrectly causing us to wire up extra lines.

This bug didn't cause any visible effects, because we only connect
up a device to the "primary" ID values (1, 4) and (1, 5), so the
extra lines would never be set to a level.

Peter Maydell 771dee52c0 hw/arm/exynos4210: Coalesce board_irqs and irq_table
The exynos4210 code currently has two very similar arrays of IRQs:

 * board_irqs is a field of the Exynos4210Irq struct which is filled
   in by exynos4210_init_board_irqs() with the appropriate qemu_irqs
   for each IRQ the board/SoC can assert
 * irq_table is a set of qemu_irqs pointed to from the
   Exynos4210State struct.  It's allocated in exynos4210_init_irq,
   and the only behaviour these irqs have is that they pass on the
   level to the equivalent board_irqs[] irq

The extra indirection through irq_table is unnecessary, so coalesce
these into a single irq_table[] array as a direct field in
Exynos4210State which exynos4210_init_board_irqs() fills in.

Move the call to the hook that writes the secondary boot stub code so

Peter Maydell 9437a76e10 hw/arm/versal: Let boot.c handle PSCI enablement
Instead of setting the CPU psci-conduit and start-powered-off
properties in the xlnx-versal-virt board code, set the arm_boot_info
psci_conduit field so that the boot.c code can do it.

This will fix a corner case where we were incorrectly enabling PSCI
emulation when booting guest code into EL3 because it was an ELF file
passed to -kernel.  (EL3 guest code started via -bios, -pflash, or
the generic loader was already being run with PSCI emulation
disabled.)

Note that EL3 guest code has no way to turn on the secondary CPUs
because there's no emulated power controller, but this was already
true for EL3 guest code run via -bios, -pflash, or the generic
loader.

Peter Maydell 817e2db8ce hw/arm/boot: Support setting psci-conduit based on guest EL
Currently we expect board code to set the psci-conduit property on
CPUs and ensure that secondary CPUs are created with the
start-powered-off property set to false, if the board wishes to use
QEMU's builtin PSCI emulation.  This worked OK for the virt board
where we first wanted to use it, because the virt board directly
creates its CPUs and is in a reasonable position to set those
properties.  For other boards which model real hardware and use a
separate SoC object, however, it is more awkward.  Most PSCI-using
boards just set the psci-conduit board unconditionally.

This was never strictly speaking correct (because you would not be
able to run EL3 guest firmware that itself provided the PSCI
interface, as the QEMU implementation would overrule it), but mostly
worked in practice because for non-PSCI SMC calls QEMU would emulate
the SMC instruction as normal (by trapping to guest EL3).  However,
we would like to make our PSCI emulation follow the part of the SMCC
specification that mandates that SMC calls with unknown function
identifiers return a failure code, which means that all SMC calls
will be handled by the PSCI code and the "emulate as normal" path
will no longer be taken.

We tried to implement that in commit 9fcd15b919
("arm: tcg: Adhere to SMCCC 1.3 section 5.2"), but this
regressed attempts to run EL3 guest code on the affected boards:
 * mcimx6ul-evk, mcimx7d-sabre, orangepi, xlnx-zcu102
 * for the case only of EL3 code loaded via -kernel (and
   not via -bios or -pflash), virt and xlnx-versal-virt
so for the 7.0 release we reverted it (in commit 4825eaae4f).

This commit provides a mechanism that boards can use to arrange that
psci-conduit is set if running guest code at a low enough EL but not
if it would be running at the same EL that the conduit implies that
the QEMU PSCI implementation is using.  (Later commits will convert
individual board models to use this mechanism.)

We do this by moving the setting of the psci-conduit and
start-powered-off properties to arm_load_kernel().  Boards which want
to potentially use emulated PSCI must set a psci_conduit field in the
arm_boot_info struct to the type of conduit they want to use (SMC or
HVC); arm_load_kernel() will then set the CPUs up accordingly if it
is not going to start the guest code at the same or higher EL as the
fake QEMU firmware would be at.

Board/SoC code which uses this mechanism should no longer set the CPU
psci-conduit property directly.  It should only set the
start-powered-off property for secondaries if EL3 guest firmware
running bare metal expects that rather than the alternative "all CPUs
start executing the firmware at once".

Note that when calculating whether we are going to run guest
code at EL3, we ignore the setting of arm_boot_info::secure_board_setup,
which might cause us to run a stub bit of guest code at EL3 which
does some board-specific setup before dropping to EL2 or EL1 to
run the guest kernel. This is OK because only one board that
enables PSCI sets secure_board_setup (the highbank board), and
the stub code it writes will behave the same way whether the
one SMC call it makes is handled by "emulate the SMC" or by
"PSCI default returns an error code". So we can leave that stub
code in place until after we've changed the PSCI default behaviour;
at that point we will remove it.

Yanan Wang 31511b6fe0 hw/arm/virt: Only describe cpu topology since virt-6.2
On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.

Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

Peter Delevoryas 5d63d0c76c hw/arm/aspeed: Allow machine to set UART default
When you run QEMU with an Aspeed machine and a single serial device
using stdio like this:

    qemu -machine ast2600-evb -drive ... -serial stdio

The guest OS can read and write to the UART5 registers at 0x1E784000 and
it will receive from stdin and write to stdout. The Aspeed SoC's have a
lot more UART's though (AST2500 has 5, AST2600 has 13) and depending on
the board design, may be using any of them as the serial console. (See
"stdout-path" in a DTS to check which one is chosen).

Most boards, including all of those currently defined in
hw/arm/aspeed.c, just use UART5, but some use UART1. This change adds
some flexibility for different boards without requiring users to change
their command-line invocation of QEMU.

I tested this doesn't break existing code by booting an AST2500 OpenBMC
image and an AST2600 OpenBMC image, each using UART5 as the console.

Then I tested switching the default to UART1 and booting an AST2600
OpenBMC image that uses UART1, and that worked too.
