In the original model, each subsystem (PSP, SSP, and TSP) created its own
set of 13 UART devices, resulting in a total of 39 UART instances. However,
on real AST2700 hardware, there is only one set of 13 UARTs shared among
all processors.
This commit reworks the UART handling to correctly model the shared
hardware design. The PSP now creates the full set of 13 UART instances,
while the SSP and TSP link to the corresponding shared UART device
through object properties.
Changes include:
- Add "DEFINE_PROP_LINK("uart", ...)" and "DEFINE_PROP_INT32("uart-dev", ...)"
to allow each coprocessor to reference a specific shared UART instance.
- Modify SSP to link to PSP’s UART4, and TSP to link to PSP’s UART7.
- Introduce "uart_alias" to remap the UART’s MMIO region into the coprocessor’s
memory space.
- Redirect the UART interrupt to the coprocessor’s NVIC, replacing the
default routing to the PSP’s GIC.
With this change, only one set of 13 UART devices is instantiated by the PSP,
while the SSP and TSP reuse them via aliasing and shared interrupt routing,
matching the real AST2700 hardware behavior.

AST2700 has a single SCU hardware block, memory-mapped at
0x12C02000–0x12C03FFF from the perspective of the main CA35 processor (PSP).
The SSP and TSP coprocessors access this same SCU block at different
addresses: 0x72C02000–0x72C03FFF.
Previously, each subsystem (PSP, SSP, and TSP) instantiated its own SCU
device, resulting in three independent SCU instances in the QEMU model.
In real hardware, however, only a single SCU exists and is shared among
all processors.
This commit reworks the SCU model to correctly reflect the hardware
behavior by allowing SSP and TSP to reference the PSP’s SCU instance.
The following changes are introduced:
- Add a scu property to AspeedCoprocessorState for linking the
coprocessor to the PSP’s SCU instance.
- Replace per-coprocessor SCU instantiation with a shared SCU link.
- Add "MemoryRegion scu_alias" to model address remapping for SSP and TSP.
- Create SCU alias regions in both SSP and TSP coprocessors and map
them at 0x72C02000 to mirror the PSP’s SCU registers.
- Ensure the SCU device in PSP is realized before SSP/TSP alias setup.
With this change, PSP, SSP, and TSP now share a consistent SCU state,
matching the single-SCU hardware design of AST2700.

AST2700 has a 128KB SRAM, physically mapped at 0x10000000–0x1001FFFF for
the PSP (CA35) processor. The SSP coprocessor shares this same SRAM but
accesses it through a different address window at 0x70000000–0x7001FFFF.
To model this shared-memory behavior in QEMU, this commit introduces a
linked SRAM property and alias mapping between the PSP and SSP subsystems.
Changes include:
- Add a "MemoryRegion *sram" link and "MemoryRegion sram_alias" to
AspeedCoprocessorState.
- Register the new "sram" property in aspeed_coprocessor_common.c.
- In aspeed_ast27x0-fc.c, connect the SSP coprocessor’s "sram" link to
the PSP’s SRAM region.
- In aspeed_ast27x0-ssp.c, create an alias mapping for SRAM at
0x70000000 – 0x7001FFFF in the SSP’s memory map.
This ensures that the SSP can correctly access the shared SRAM contents
through its own address space while maintaining a consistent physical
backing region. It also guarantees that the SRAM is realized before the
SSP device, ensuring successful alias setup.

Now that we have a simple decoding logic for all the banked registers,
remove the register API usage for them. This restricts the register API
usage to only the base registers (from 0x0 to 0xec).
This also removes all the custom code that was creating register
descriptors for the register API and was leading to memory leaks when
the device was finalized.

Introduce the REGISTER_ARRAY QOM type. This type reuses the existing
RegisterInfoArray struct. When `register_init_block' is called, it creates
a REGISTER_ARRAY object and parents it to the calling device. This way
it gets finalized when the device is. The memory region is parented to
the REGISTER_ARRAY object to ensure correct finalizing order.
The finalize function of the REGISTER_ARRAY type performs the necessary
cleaning that used to be done by `register_finalize_block'. The latter
is left empty and will be removed when all the register API users have
been refactored.

The REGISTER class (RegisterInfo struct) is currently a QOM type
inheriting from DEVICE. This class has no real purpose:
- the qdev API is not used,
- according to the comment preceding it, the object_initialize call
is here to zero-initialize the struct. However all the effective
struct attributes are then initialized explicitly.
- the object is never parented.
This commits drops the REGISTER QOM type completely, leaving the
RegisterInfo struct as a bare C struct.
The register_register_types function is left empty here because it is
reused in the next commit.

Rename the AST27x0 TSP type from TYPE_ASPEED27X0TSP_SOC to
TYPE_ASPEED27X0TSP_COPROCESSOR to align with the naming convention used
for the SSP coprocessor (TYPE_ASPEED27X0SSP_COPROCESSOR).
This change clarifies that TSP is implemented as a coprocessor rather than
a full SoC.
This ensures consistent terminology between SSP and TSP components and
improves clarity within the coprocessor subsystem code.

Refactor the AST27x0 SSP implementation to use the unified
Aspeed27x0CoprocessorState structure shared between SSP and TSP.
Previously, SSP and TSP each defined separate state structures
(Aspeed27x0SSPSoCState and Aspeed27x0TSPSoCState), which contained
identical members and caused unnecessary code duplication.
This change removes Aspeed27x0SSPSoCState and replaces it with
Aspeed27x0CoprocessorState, consolidating shared coprocessor state fields
into a single definition in aspeed_coprocessor.h.

Add a new AspeedCoprocessor class that defines the foundational structure for
ASPEED coprocessor models. This class encapsulates a base DeviceState with
links to system memory, clock, and peripheral components such as SCU, SCUIO,
Timer Controller, and UARTs.
Introduce the corresponding implementation file
aspeed_coprocessor_common.c, which provides the aspeed_coprocessor_realize()
method, property registration, and QOM type registration. The class is marked
as abstract and intended to serve as a common base for specific coprocessor
variants (e.g. SSP/TSP subsystems).
This establishes a reusable and extensible framework for modeling ASPEED
coprocessor devices.
