The BSP family and MCU option were named "ch58x"/"CH58X", but the supported part is the CH583/CH582 (and the SDK repo is openwch/ch583); CH585 is a separate MCU family, so the CH58x umbrella was misleading. Rename to the specific family: - hw/bsp/ch58x -> hw/bsp/ch583 (dir), and the BSP-local files ch58x_it.* -> ch583_it.*, system_ch58x.* -> system_ch583.* (include guards/refs updated). The vendor SDK files (CH58x_common.h, CH58x_*.c in hw/mcu/wch/ch583) keep their names. - OPT_MCU_CH58X -> OPT_MCU_CH583 in tusb_option.h, tusb_mcu.h, and the shared WCH USBFS driver (ch32_usbfs_reg.h, dcd_ch32_usbfs.c). OPT_MCU_CH582 is kept as an alias (same value), so either name selects the same code. - FAMILY_MCUS CH58X -> CH583, CFG_TUSB_MCU=OPT_MCU_CH583, mcu:CH58X -> mcu:CH583 in the example skip lists, the CI build matrix (ci_set_matrix.py), the get_deps family tag, and docs/reference/boards.rst. Board names (ch582m_evt, yd-ch582m) are unchanged. Verified: make + cmake build for ch582m_evt, and ci.lan HIL (all device examples pass).
