From a3dcf633584b50842b965e4f4896ee0e05e6eb85 Mon Sep 17 00:00:00 2001 From: Jamin Lin Date: Tue, 4 Nov 2025 11:12:48 +0800 Subject: [PATCH] hw/arm/aspeed: Split Sonorapass machine into a separate source file for maintainability MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
