bsp(ch32): naked fsdev ISRs so nested USBD IRQs return safely

2026-07-09T16:38:48Z

The three USBD lines nest under QingKe HWSTK; gcc's interrupt prologue corrupts the return, so rely on the hardware stack and bare mret. Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

IAR is only supported with CMake. Remove all IAR-specific references from the Make build system including toolchain files, SRC_S_IAR, LD_FILE_IAR variables, and IAR toolchain detection. Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and broken formatting in stm32f7 board_uart_write. Co-Authored-By: Claude Opus 4.6 (1M context)
