Previously, the SSP memory was incorrectly modeled as "SRAM" with
a 32 MB size. This change introduces a new sdram field in
AspeedCoprocessorState and updates the realization logic accordingly.
Rename from SRAM to SDRAM and correct size from 32MB to 512MB to match
hardware.

From: Jamin Lin <jamin_lin@aspeedtech.com>
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.

AST2700 has a 128KB SRAM, physically mapped at 0x10000000–0x1001FFFF for
the PSP (CA35) processor. The TSP 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 TSP subsystems.
Changes include:
- Add the SRAM alias mapping at 0x70000000 in aspeed_ast27x0-tsp.c.
- In aspeed_ast27x0-fc.c, connect the TSP coprocessor’s "sram" link to
the PSP’s SRAM region.
- Ensure the alias region is initialized during TSP SoC realization so
the TSP can correctly access shared SRAM through its own address space.
This ensures that the TSP and PSP share the same physical SRAM backing.

From: Jamin Lin <jamin_lin@aspeedtech.com>
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.

From: Cédric Le Goater @ 2025-10-22 12:29 UTC (permalink / raw)
To: qemu-arm, qemu-devel; +Cc: Jamin Lin, Cédric Le Goater
From: Jamin Lin <jamin_lin@aspeedtech.com>
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.

From: Cédric Le Goater @ 2025-10-22 12:29 UTC (permalink / raw)
To: qemu-arm, qemu-devel; +Cc: Jamin Lin, Cédric Le Goater
From: Jamin Lin <jamin_lin@aspeedtech.com>
This patch introduces a dedicated ca35_boot_rom memory region and
copies the FMC0 flash data into it.
The motivation is to support the upcoming vbootrom. The vbootrom
replaces the existing BOOTMCU (RISC-V 32 SPL) flow, which currently reads
the "image-bmc" from FMC_CS0 and loads the following components
into DRAM:
- Trusted Firmware-A
- OP-TEE OS
- u-boot-nodtb.bin
- u-boot.dtb
After loading, BOOTMCU releases the CA35 reset so that CA35 can start
executing Trusted Firmware-A.
The vbootrom follows the same sequence: CA35 fetches "image-bmc" from FMC0
flash at the SPI boot ROM base address (0x100000000), parses the FIT image,
loads each component into its designated DRAM location, and then jumps to
Trusted Firmware-A.

From: Felix Wu <flwu@google.com>
Added 32 bits property for ASPEED GPIO. Previously it can only be
access in bitwise manner.
The changes to qobject is to index gpios with array indices on top of
accessing with registers. This allows for easier gpio access,
especially in tests with complex behaviors that requires large number
of gpios at a time, like fault injection and networking behaviors.
Indexing multiple gpios at once allows qmp/side band client to no
longer hardcode and populate register names and manipulate them
faster.

The ast2600-evb machine model is using the "mx66u51235f" flash model,
which has issues with recent Linux kernels (6.15+) when reading SFDP
data.
Change the flash model to "w25q512jv", which is the model present on
some ast2600a3 EVB board and is known to work correctly with recent
kernels. Adjust the corresponding qtest to reflect the new JEDEC ID of
the w25q512jv flash.
