OpenRISC port

[Stefan Wallentowitz <stefan dot wallentowitz at tum dot de>]

Dear all,

this is my first attempt to submit my OpenRISC port which I developed 
here: https://github.com/wallento/or1k-newlib
Due to the list's message size restrictions I cannot attach the patches:

  - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0001-OpenRISC-Add-no-delay-slot-support.patch

  - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0002-libgloss-OpenRISC-support.patch

  - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0003-newlib-OpenRISC-Baremetal-support.patch

The port is based on the never-upstreamed port maintained by the 
OpenRISC community. This one was unfortunately GPL and I corresponded 
with all authors in the final port to change the license to BSD.

The port is twofold: A rather large libgloss that contains a lot of 
baremetal support functions to handle exceptions, interrupts, etc. 
easily. Beside this, I added a sys folder for the or1k-elf target that 
uses dynamic reentrancy and depends on libgloss. The machine folder is 
still compatible with the or1k-rtems toolchain. I am really not sure if 
this is the way to go, so please comment on other ways.

The port already contains multicore support with a shared heap and 
private stacks, reentrancy data structures and port internal data 
structures.

I am looking forward to your feedback and hope the code quality is above 
your expectations on a guy from academia ;)

Best regards,
Stefan
