void dcache_clean_range(unsigned start,unsigned size)
{
    unsigned st,end,i;
    st=start&(~(CACHE_LINE_SIZE-1));
    end=start+size;
    for(i=st; i<end; i+=CACHE_LINE_SIZE)
    {
        dcache_clean_line(i);
    }
#ifdef CONFIG_CACHE_L2X0
    l2x0_wait_clean();

}

Example #2

File: cache.c Project: 01hyang/u-boot

void dcache_clean_range(volatile void *start, size_t size)
{
	unsigned long v, begin, end, linesz;

	linesz = CONFIG_SYS_DCACHE_LINESZ;

	/* You asked for it, you got it */
	begin = (unsigned long)start & ~(linesz - 1);
	end = ((unsigned long)start + size + linesz - 1) & ~(linesz - 1);

	for (v = begin; v < end; v += linesz)
		dcache_clean_line((void *)v);

	sync_write_buffer();
