On i386 builds, I'm seeing

build-r7137.out:mtd_dataflash.c:(.text+0x10dff4): undefined reference to `__umoddi3'
build-r7137.out:mtd_dataflash.c:(.text+0x10e010): undefined reference to `__umoddi3'
build-r7137.out:mtd_dataflash.c:(.text+0x10e09f): undefined reference to `__udivdi3'

which are caused by % and / operations where the denominator is a variable:

	/* Sanity checks */
	if ((instr->addr + instr->len) > mtd->size
			|| (instr->len % priv->page_size) != 0
			|| (instr->addr % priv->page_size) != 0)
		return -EINVAL;

...
		/* Calculate flash page address; use block erase (for speed) if
		 * we're at a block boundary and need to erase the whole block.
		 */
		pageaddr = instr->addr / priv->page_size;
