## Summary Initialize the FPU and enable the FZ (flush-to-zero) trap for TriCore TC4xx processors. This ensures floating-point divide-by-zero exceptions are properly caught and reported via the trap handler. ## Changes - Add `ARCH_HAVE_FPU` selection for TC4xx (excluding CSRM core) - Add `tricore_fpu.c` with FPU initialization (enable FZ trap) - Add FPU trap register definitions in `irq.h` - Add FPU sync/async trap reporting in trap handler - Call `tricore_fpuinit()` during core startup ## Testing - Build: `triboard_tc4x9_com:nsh` (gcc) ✅ - Boot verification on TC4D9 EVB ✅ Internal-Ref: 01f9b99bb5947e01a4cf55ae04ab6abaf0645a07 Signed-off-by: zhangyuan29 <[email protected]> -- This is an automated message from the Apache Git Service.
