lwIP for beaglebone black

[Marcos Díaz]

Hi, here I will attach two repos with our work so far:

https://bitbucket.org/mdmarcosdiaz/lwip-bbb-rtems/  (Branch POSIX-API-LWIP)
 This is the LWIP with our drivers copied from TI's and modified to
support RTEMS tasks.
It has a makefile that generates a library.

To make it work we used the bbb bsp from Ben Gras, and we had to make
some changes to disable the cache, and to fix a problem from the main
rtems that it was fixed there but not in this local repository.
Perhaps it will be best to make it run in the bsp that is in the
mainline of RTEMS, but this repo will help you to see what changes we
had to make:

https://bitbucket.org/eduardo-sanchez/rtemsbbb

Please, let me know any help you need.
