I have a requirement to interface UART with an external microcontroller 
using baud rate above 4Mbps, hence following is my approach to apply
the changes. Can any one review/provide me appropriate approach.

See TCGETS2/TCSETS2 and the BOTHER flag.

The kernel supports aetting arbitary baud rates already.
