Hi Joel,

I have moved register initializations into the cr16-linux-tdep.c. This 
was also recommended by Yao. 

> Take a look at how sparc is organized, or maybe amd64.
The other targets like amd64 have plenty on stuff in this file, however it is
unrelated to this port. I feel the updated cr16-linux-tdep.c file should allow
it to build on top of the bareboard one.

Added empty lines between comment and functions

I have added comments for this and removed the unnecessary externs here.

> Don't these functions have declarations in opcode? This is really ugly
These prototypes were added recently and are part of a bfd patch. I forgot
to remove these in the last version.

> +extern const gdb_byte breakpoint_linux[];
I have removed this as it is not used in the later versions of the patch.

I have made another pass over the code and have taken care of the above 
mentioned points and other formatting nits which I could find. Thanks.

I have not attached my updated patch here. I am working on Yao's comments
and will attach it in that reply.
