nuttx/tools/configure.c
Anjana fae7e63479 We have ported NuttX on Renesas RX65N Micro-controller. This port includes following interfaces 
1. Serial (UART) driver (13 ports)
2. Ethernet driver

This port is provided on two boards
1. RSK RX65N-2MB
2. GR-Rose

The port is built on Cygwin environment.

As part of this port, we have created two documents
1. Readme.txt for each board
2. User manual to provide information about development environment setup
Both these documents are placed under
1. /boards/renesas/rx65n/rx65n-grrose
2. /boards/renesas/rx65n/rx65n-rsk2mb

We have run 'nxstyle' for coding guidelines and 'ostest' for testing NuttX features on test platform.
We have shared the log with no errors as confirmation of valid port.
