Perhaps you could just look at the startup_stm32f0xx.s for inspiration?

Calling C functions

        IMPORT  SystemInit

                 LDR     R0, =SystemInit
                 BLX     R0

void SystemInit(void)
{
 // ..
}

Calling ASM functions

foo PROC
    EXPORT foo

    bx lr

    ENDP ; foo

extern void foo(void);

foo();
