这家伙很懒，什么也没写！

是否考虑把硬件层驱动与数据链路层的接口标准化呢?
如在两个bsp里同为串口驱动,接口却不一样...
[http://rt-thread.googlecode.com/svn/trunk/bsp/lpc176x/uart.c](http://rt-thread.googlecode.com/svn/tru ... 76x/uart.c)
里面的接口:
struct rt_uart_lpc
void UART0_IRQHandler(void)
static rt_err_t rt_uart_init (rt_device_t dev)
static rt_err_t rt_uart_open(rt_device_t dev, rt_uint16_t oflag)
static rt_err_t rt_uart_close(rt_device_t dev)
static rt_size_t rt_uart_read(rt_device_t dev, rt_off_t pos, void* buffer, rt_size_t size)
static rt_size_t rt_uart_write(rt_device_t dev, rt_off_t pos, const void* buffer, rt_size_t size)
void rt_hw_uart_init(void)
而在http://rt-thread.googlecode.com/svn/trunk/bsp/lpc2148/drivers/serial.c
的接口:
struct rt_lpcserial
void rt_hw_uart_isr(struct rt_lpcserial* lpc_serial)
void rt_hw_uart_isr_1(int irqno)
void rt_hw_uart_isr_2(int irqno)
static rt_err_t rt_serial_init (rt_device_t dev)
static rt_err_t rt_serial_open(rt_device_t dev, rt_uint16_t oflag)
static rt_err_t rt_serial_close(rt_device_t dev)
static rt_err_t rt_serial_control(rt_device_t dev, rt_uint8_t cmd, void *args)
static rt_size_t rt_serial_read(rt_device_t dev, rt_off_t pos, void* buffer, rt_size_t size)
static rt_size_t rt_serial_write(rt_device_t dev, rt_off_t pos, const void* buffer, rt_size_t size)
void rt_hw_serial_init(void)

是否考虑把基本设备驱动定义到一个标准的的头文件里, 各个bsp编写对应的.c文件.形成rtt统一的驱动层接口?
