ENGR00258357-5: mlb: Use circle buf macros to replace old ringbuf mechanism Use circle buf to replace old ringbuf mechanism. Change to use circle buffer in read, write, rx isr and tx isr functions. In first design of MLB, it's using it's own mechanism to manage ring buffer, like in mxc_mlb.c. And then, I saw that kernel already had a serials of circ buffer macros which can be used to manage ring buffers. This patch is to use circle buffer macros to manage mlb internal ring buffers. For detail of circle buffers, you can refer to linux-2.6-imx/Documentation/circular-buffers.txt. Signed-off-by: Terry Lv <r65388@freescale.com>
