eboot 中的flash.c中的CFI_Write_Block在哪里定义的？

如题

就是经常能见到的所谓的微软提供的代码里面：
比如：

BOOL OEMWriteFlash(DWORD dwStartAddr, DWORD dwLength)
{
    //EdbgOutputDebugString("OEMWriteFlash 0x%x 0x%x\r\n", dwStartAddr, dwLength);

/*	DWORD dwFlashAddr, dwExtraBytes = 0;
	LPBYTE pbCache = NULL;
	UCHAR nNumBlocks = 0;


    //确认起始地址和长度都在Flash区域内 
	if(!OEMIsFlashAddr(dwStartAddr) || !OEMIsFlashAddr(dwStartAddr + dwLength - 1)) 
	{
		return(FALSE);
	}

    //确认起始地址是Block字节对齐的 
	if (dwStartAddr % FLASH_BLOCK_SIZE)
	{
		return(FALSE);
	}

	//计算要写入的block数量 
 	nNumBlocks   = (UCHAR) (dwLength/FLASH_BLOCK_SIZE);
	dwExtraBytes = (dwLength % FLASH_BLOCK_SIZE);
	dwFlashAddr  = dwStartAddr;
	pbCache      = OEMMapMemAddr (dwStartAddr, dwFlashAddr);


    //写Flash  
    while(nNumBlocks)
    {  
        if (CFI_Write_Block((DWORD*)dwFlashAddr, (DWORD*)pbCache, FLASH_BLOCK_SIZE, NULL) != PASS)
        {
            EdbgOutputDebugString("ERROR: OEMWriteFlash - unable to write to block (block address=0x%x).\r\n", dwFlashAddr);
            return(FALSE);
        }

        dwFlashAddr += FLASH_BLOCK_SIZE;
        pbCache = OEMMapMemAddr (dwStartAddr, dwFlashAddr);
        --nNumBlocks;
    }

    //将额外的数据写入Flash中 
	if(dwExtraBytes)
    {
		if (CFI_Write_Block((DWORD*)dwFlashAddr, (DWORD*)pbCache, dwExtraBytes, NULL) != PASS)
        {
            EdbgOutputDebugString("ERROR: OEMWriteFlash - unable to write to block (block address=0x%x).\r\n", dwFlashAddr);
            return(FALSE);
        }
    }
*/

	return TRUE;
}

具体点，我的flash.c里面没有么
