6820588efa hw/arm: ast2600: Correct the iBT interrupt ID
The AST2600 allocates distinct GIC IRQs for the LPC subdevices such as
the iBT device. Previously on the AST2400 and AST2500 the LPC subdevices
shared a single LPC IRQ.

b151de69f6 hw/arm: ast2600: Set AST2600_MAX_IRQ to value from datasheet
The datasheet says we have 197 IRQs allocated, and we need more than 128
to describe IRQs from LPC devices. Raise the value now to allow
modelling of the LPC devices.

957ad79f73 hw/arm: ast2600: Force a multiple of 32 of IRQs for the GIC
This appears to be a requirement of the GIC model. The AST2600 allocates
197 GIC IRQs, which we will adjust shortly.

a4ea92013d arm/ast2600: Fix SMP booting with -kernel
The ast2600 machines do not have PSCI firmware, so this property should
have never been set. Removing this node fixes SMP booting Linux kernels
that have PSCI enabled, as Linux fails to find PSCI in the device tree
and falls back to the soc-specific method for enabling secondary CPUs.

The comment is out of date as Qemu has supported -kernel booting since
9bb6d14081 ("aspeed: Add boot stub for smp booting"), in v5.1.

Fixes: f25c0ae107 ("aspeed/soc: Add AST2600 support")

The AN524 has a USB controller (an ISP1763); we don't have a model of

MemoryRegion with both the ethernet controller and an

25ff112a8c hw/arm/mps2-tz: Add new mps3-an524 board
Add support for the mps3-an524 board; this is an SSE-200 based FPGA
image, like the existing mps2-an521.  It has a usefully larger amount
of RAM, and a PL031 RTC, as well as some more minor differences.

In real hardware this image runs on a newer generation of the FPGA
board, the MPS3 rather than the older MPS2.  Architecturally the two
boards are similar, so we implement the MPS3 boards in the mps2-tz.c
file as variations of the existing MPS2 boards.

424182791b hw/arm/mps2-tz: Allow PPCPortInfo structures to specify device interrupts
The mps2-tz code uses PPCPortInfo data structures to define what
devices are present and how they are wired up.  Currently we use
these to specify device types and addresses, but hard-code the
interrupt line wiring in each make_* helper function.  This works for
the two boards we have at the moment, but the AN524 has some devices
with different interrupt assignments.

This commit adds the framework to allow PPCPortInfo structures to
specify interrupt numbers.  We add an array of interrupt numbers to
the PPCPortInfo struct, and pass it through to the make_* helpers.
The following commit will change the make_* helpers over to using the
framework.

fee887a7b0 hw/arm/mps2-tz: Correct wrong interrupt numbers for DMA and SPI
On the MPS2 boards, the first 32 interrupt lines are entirely
internal to the SSE; interrupt lines for devices outside the SSE
start at 32.  In the application notes that document each FPGA image,
the interrupt wiring is documented from the point of view of the CPU,
so '0' is the first of the SSE's interrupts and the devices in the
FPGA image itself are '32' and up: so the UART 0 Receive interrupt is
32, the SPI #0 interrupt is 51, and so on.

Within our implementation, because the external interrupts must be
connected to the EXP_IRQ[0...n] lines of the SSE object, we made the
get_sse_irq_in() function take an irqno whose values start at 0 for
the first FPGA device interrupt.  In this numbering scheme the UART 0
Receive interrupt is 0, the SPI #0 interrupt is 19, and so on.

The result of these two different numbering schemes has been that
half of the devices were wired up to the wrong IRQs: the UART IRQs
are wired up correctly, but the DMA and SPI devices were passing
start-at-32 values to get_sse_irq_in() and so being mis-connected.

Fix the bug by making get_sse_irq_in() take values specified with the
same scheme that the hardware manuals use, to avoid confusion.

8e4b4c1ca6 hw/misc/mps2-scc: Implement CFG_REG5 and CFG_REG6 for MPS3 AN524
The AN524 version of the SCC interface has different behaviour for
some of the CFG registers; implement it.

Each board in this family can have minor differences in the meaning
of the CFG registers, so rather than trying to specify all the
possible semantics via individual device properties, we make the
behaviour conditional on the part-number field of the SCC_ID register
which the board code already passes us.

For the AN524, the differences are:
 * CFG3 is reserved rather than being board switches
 * CFG5 is a new register ("ACLK Frequency in Hz")
 * CFG6 is a new register ("Clock divider for BRAM")

We implement both of the new registers as reads-as-written.

must be wired to all CPUs by creating IRQ splitter devices for the
AN521, because it has 2 CPUs, but wiring the device IRQ directly to
the SSE/IoTKit input for the AN505, which has only 1 CPU.

We can avoid making an explicit check on the board type constant by
instead creating and using the IRQ splitters for any board with more
than 1 CPU.  This avoids having to add extra cases to the
conditionals every time we add new boards.
