This commit moves the OpenPOWER Palmetto BMC machine implementation out of aspeed.c into a new standalone file aspeed_ast2400_palmetto.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 PALMETTO_BMC_HW_STRAP1 macro definition from into the new file. - Moved palmetto_bmc_i2c_init() I²C initialization logic into the new file. - Moved aspeed_machine_palmetto_class_init() and type registration. - Added aspeed_ast2400_palmetto.c to the build system (meson.build). - Removed all Palmetto-specific code and macros from aspeed.c. No functional changes.
