feat[bsp][stm32][h7]: add UART4 RX DMA configuration

2026-09-21T01:36:49Z

Add the missing UART4 RX DMA definitions for STM32H7. UART4 RX DMA uses DMA1 Stream0 with the UART4 RX DMA request. The configuration is enabled when BSP_UART4_RX_USING_DMA is selected.

- Unify DMA/BDMA/GPDMA descriptors in drv_dma (common fields + per-type union) - Support BDMA in SPI driver with h7 dma/spi config header updates - Add SPI6 TX/RX BDMA Kconfig options for H7

[arm][cortex-m4] Add hardware stack guard support

2026-08-26T02:37:02Z

Enable RT_USING_HW_STACK_GUARD on Cortex-M4, which was previously only available on Cortex-M7 and Cortex-M33. Core porting (libcpu/arm/cortex-m4/): - Add mpu.c/mpu.h/mputype.h aligned with the Cortex-M7 MPU layer. The only difference is the default memory type attribute: Cortex-M4 has no L1 cache, so the cacheability bits are reduced to three cases. - Add rt_hw_stack_guard_init() to cpuport.c. - Add missing #include to context_gcc.S and invoke rt_hw_mpu_table_switch() in the PendSV context switch path. - Update SConscript to exclude mpu.c when memory protection is disabled. BSP reference (bsp/stm32/stm32f407-fk407m2-zgt6/): - board.h: include rtthread.h and define NUM_STATIC_REGIONS. - board.c: define static_regions[] marking the Flash region read-only, guarded by RT_USING_MEM_PROTECTION so it is not enabled by default.

[rust][tools] Fix Rust build example configuration handling

2026-08-21T03:17:57Z

Improve the Rust build integration across core, applications, components, and module examples. Fix build failure propagation, target and feature handling, linker flags, example configuration semantics, and add STM32 CI attach coverage.
