This a naive implementation of BOOTP/TFTPBOOT, the protocols
to use to bootstrap a computer through a TCP/IP network.
The goal was to design a small footprint implementation
to allow the code to be integrated into a monitor program
stored in a ROM/FLASH, the footprint is about 7 KBytes
for the test program.
This code has not been yet tested in many environment.
It should be seen at your starting point to integrate
the network boot function to your board.
