Functions
void	anonymous_namespace{StmSpi.cpp}::CopyFromMaybeFmcToAxi (uint8_t *dst, const uint8_t *src, hf_u16_t len) noexcept
	Copy len bytes from src into internal-SRAM dst via aligned 32-bit loads (safe when src may be external RAM / task stack).
void	anonymous_namespace{StmSpi.cpp}::CopyFromAxiToMaybeFmc (uint8_t *dst, const uint8_t *src, hf_u16_t len) noexcept
	Publish internal-SRAM src into dst via aligned 32-bit RMW (safe when dst may be external RAM / task stack).
