The question about the UART on UCC5,UCC6,UCC7,UCC8 for MPC8360?

The question about the UART on UCC5,UCC6,UCC7,UCC8 for MPC8360?

[郭劲]

Hi,friends,

 I runed the LTIB for MPC8360,selected "configure the kernel", then the make
menuconfig is appeared,that is "linux kernel configuration". I config QE to
follow
style: 
UCC1,GETH;
UCC2,GETH; 
UCC5,UART;
UCC6,UART;
UCC7,UART;
UCC8,UART. 

  after compiled, I download the linux to MPC8360 board, but I cannot find the
serial device for UCC5,UCC6,UCC7,UCC8. I just find the ttyS0,ttyS1 is OK.
  Could you tell me that what's the name for the serial device of UCC5,6,7,8?
  Whether or not I can use those UART just like the ttyS0,ttyS1?

I don't know why the BSP offers a UART driver for the 8360, because the driver 
isn't available yet.  I'm working on that, though.  I'll post the driver in a 
week or so, and it will be included in 2.6.25.  You'll have to ask the BSP 
support line if they plan on updating the BSP to include the new driver.
