1. Move "AspeedMachineState" definition to a shared header.
2. Make common helper functions globally accessible.
3. Split each AST2500 machine into its own source file:
- FP5280G2
- G220A
- Tiogapass
- YosemiteV2

Aspeed machines will be moved into split C files for better
modularization and future maintenance.
To allow all machine implementations to reuse the same
AspeedMachineState structure, the struct definition is moved
from aspeed.c to the shared header aspeed.h.
This change centralizes the common state structure used across
all Aspeed machine models, reduces redundancy, and simplifies
future refactoring work for new machines.
No functional changes.

The function aspeed_machine_class_init_cpus_defaults() is now made
globally visible so that it can be used by other Aspeed machine C files.
Previously, this function was declared as static, restricting its
visibility to aspeed.c. Since future machine split files will also
need to call this helper to initialize default CPU settings, its
declaration has been moved to the common header aspeed.h and the
static keyword has been removed.
No functional changes.

The helper function create_pca9552() is now made globally visible
so it can be reused by different Aspeed machine source files.
Previously, the function was declared static, limiting its scope
to aspeed.c. Since multiple Aspeed machine implementations will
require I²C device initialization using PCA9552 GPIO expanders,
this function has been promoted to global visibility.
This change improves code sharing and reduces duplication across
machine-specific initialization files.
No functional changes.

The function create_pca9554() is now made globally accessible so that
it can be reused by different Aspeed machine source files.
Originally, this helper was declared static inside aspeed.c,
restricting its visibility. As future Aspeed machine implementations
will also require PCA9554 I²C device setup, the function has been
exported by removing the static keyword and adding its prototype
to aspeed.h.
This change promotes better code reuse and consistency across
machine initialization code.
No functional changes.

This commit moves the FP5280G2 BMC machine implementation from
aspeed.c into a new standalone file aspeed_ast2500_fp5280g2.c.
The change improves code organization and prepares the Aspeed
machine framework for future expansion and easier maintenance.
Key updates include:
- Moved fp5280g2_bmc_i2c_init() and related machine class init
functions into aspeed_ast2500_fp5280g2.c.
- Added new file to hw/arm/meson.build for compilation.
- Removed obsolete FP5280G2 definitions from aspeed.c
No functional changes.

This commit refactors the Bytedance G220A BMC machine by moving its
implementation from aspeed.c into a new dedicated file
aspeed_ast2500_g220a.c.
The goal is to improve modularity and maintainability of Aspeed
machine definitions by isolating each platform into its own source
file. This aligns with ongoing efforts to simplify aspeed.c,
which previously contained all machine configurations.
Key updates include:
- Moved G220A_BMC_HW_STRAP1 definition and
g220a_bmc_i2c_init() function into aspeed_ast2500_g220a.c.
- Moved aspeed_machine_g220a_class_init() and related type
registration to the new file.
- Added the new file to the build system (meson.build).
- Removed all G220A-specific code from aspeed.c.
No functional changes.

This commit moves the Tiogapass BMC machine implementation out of
aspeed.c into a new dedicated file aspeed_ast2500_tiogapass.c.
To support splitting Tiogapass into a dedicated source file,
a new TIOGAPASS_BMC_HW_STRAP1 macro is added as a copy of
AST2500_EVB_HW_STRAP1.
The change follows the ongoing effort to modularize Aspeed platform
support by splitting each machine definition into its own source file.
This makes aspeed.c cleaner, easier to maintain, and simplifies
future feature additions or refactoring for individual machines.
Key updates include:
- Removed tiogapass_bmc_i2c_init() and its FRU data from aspeed.c
and aspeed_eeprom.c.
- Removed Tiogapass type registration from aspeed_machine_types[].
- Added new source file aspeed_ast2500_tiogapass.c to meson.build.
- Removed unused Tiogapass FRUID declarations from aspeed_eeprom.h.
No functional changes.

This commit moves the YosemiteV2 BMC machine implementation from
aspeed.c into a new standalone file aspeed_ast2500_yosemitev2.c.
To support splitting YosemiteV2 into a dedicated source file,
a new YOSEMITEV2_BMC_HW_STRAP1 macro is added as a copy of
AST2500_EVB_HW_STRAP1.
The refactor is part of an ongoing effort to modularize Aspeed
machine definitions by separating each board into its own source
file. This improves code readability, maintainability, and simplifies
future platform-specific changes.
Key updates include:
- Moved yosemitev2_bmc_i2c_init() and its FRU data into a new file.
- Removed aspeed_machine_yosemitev2_class_init() and type registration
from aspeed.c.
- Removed YosemiteV2 FRUID data and declarations from
aspeed_eeprom.c and aspeed_eeprom.h.
- Added aspeed_ast2500_yosemitev2.c to the build system
(meson.build).
No functional changes.

This commit moves the Witherspoon BMC machine implementation out of
aspeed.c and into a new dedicated file aspeed_ast2500_witherspoon.c.
To support splitting Witherspoon into a dedicated source file,
a new WITHERSPOON_BMC_HW_STRAP1 macro is added as a copy of
ROMULUS_BMC_HW_STRAP1.
The change is part of a broader effort to modularize Aspeed board
definitions, allowing each machine type to be maintained and updated
independently. By isolating Witherspoon logic, the aspeed.c file
becomes cleaner and easier to manage as more platforms are added.
Key updates include:
- Moved witherspoon_bmc_i2c_init() and related LED setup code into
aspeed_ast2500_witherspoon.c.
- Added WITHERSPOON_BMC_HW_STRAP1 replacement macro for local use.
- Removed aspeed_machine_witherspoon_class_init() and type
registration from aspeed.c.
- Added the new file to meson.build for compilation.
No functional changes.

This commit moves the Sonorapass BMC machine implementation out of
aspeed.c and into a new standalone file aspeed_ast2500_sonorapass.c.
The refactor continues the effort to modularize Aspeed platform support
by separating each board’s implementation into its own source file.
This improves maintainability, readability, and simplifies future
updates to individual machine configurations.
Key updates include:
- Moved SONORAPASS_BMC_HW_STRAP1 definition into the new file.
- Moved sonorapass_bmc_i2c_init() and all I²C device initialization
logic from aspeed.c into aspeed_ast2500_sonorapass.c.
- Moved aspeed_machine_sonorapass_class_init() and type registration
into the new file.
- Added the new file to the build system (meson.build).
- Removed all Sonorapass-specific code and definitions from aspeed.c
No functional changes.

This commit moves the Romulus BMC machine implementation out of
aspeed.c into a new standalone file aspeed_ast2500_romulus.c.
The refactor continues the modularization of Aspeed platform
definitions, separating each board into its own C source file to
improve maintainability, readability, and reduce code clutter in
aspeed.c.
Key updates include:
- Moved ROMULUS_BMC_HW_STRAP1 definition to the new file.
- Moved romulus_bmc_i2c_init() and related I²C device setup.
- Moved aspeed_machine_romulus_class_init() and type registration
to aspeed_ast2500_romulus.c.
- Added the new file to the build system (meson.build).
- Removed all Romulus-specific code from aspeed.c.
No functional changes.

This commit moves the Supermicro X11SPI BMC machine definition from
aspeed.c into a new standalone file aspeed_ast2500_supermicro-x11spi.c,
and adds a dedicated I²C initialization function for the platform.
The refactor continues the effort to modularize Aspeed platform support,
ensuring each machine model is defined in its own source file. This improves
code organization, readability, and simplifies maintenance when adding or
modifying platform-specific behavior.
Previously, the Supermicro X11SPI machine reused
palmetto_bmc_i2c_init() for its I²C setup. To make the machine
definition fully self-contained, the function was copied and renamed
to supermicro_x11spi_bmc_i2c_init(). This ensures that the machine
can evolve independently without depending on Palmetto’s board logi
Key updates include:
- Moved SUPERMICRO_X11SPI_BMC_HW_STRAP1 macro and machine class init
(aspeed_machine_supermicro_x11spi_bmc_class_init) into a new file.
- Added new function supermicro_x11spi_bmc_i2c_init() copied from
palmetto_bmc_i2c_init() for independent control.
- Updated the machine definition to use the new I²C init function.
- Registered the new source file in meson.build.
- Removed all Supermicro X11SPI-related definitions from aspeed.c.
No functional changes.

This commit moves the AST2500 EVB machine implementation out of
aspeed.c into a new standalone file aspeed_ast2500_evb.c.
This refactor continues the modularization effort for Aspeed platform
support, placing each board’s logic in its own dedicated source file.
It improves maintainability, readability, and simplifies future
development for new platforms without cluttering aspeed.c.
Key updates include:
- Moved AST2500_EVB_HW_STRAP1 macro definition into the new file.
- Moved ast2500_evb_i2c_init() I²C initialization logic.
- Moved aspeed_machine_ast2500_evb_class_init() and type registration.
- Added aspeed_ast2500_evb.c to the build system (meson.build).
- Removed all AST2500 EVB–specific code and macros from aspeed.c.
No functional changes.
