==== Getting rid of the stdlib dep ====

I have finished the stdlib-free implementation. It's available on the [[http://git.etherboot.org/?p=people/peper/gpxe.git;a=shortlog;h=refs/heads/linux|linux branch]]. Most of the new stuff is in these commits:
  * [linux] Add linuxprefix
  * [linux] Add linux_syscall
  * [linux] Add most of the linux api
  * [linux] Add linux_realloc

I have also done some refactoring along the way, most notably the command line argument handling has been changed to not require any ''core/main.c'' changes.
  * [linux] Add command line arguments for network setup

The implementation linking to stdlib has been moved to a separate ''linuxlibc'' ''PLATFORM'' and is now on its own [[http://git.etherboot.org/?p=people/peper/gpxe.git;a=shortlog;h=refs/heads/linuxlibc|linuxlibc branch]].

Details of the implementation will follow in the notes soon.

==== Milestone reached ====

Josh did a thorough review of the codebase (thanks again!), which resulted in all kinds of changes including asm style, some refactoring and also two bigger new things:
  * [linux] Add linux platform skeleton - simple linker scripts for the libc-free linux platform
  * [linux] Add console - proper console support

Details coming to notes.

With the issues resolved Josh said pretty much everything essential is done and hence the project is ready for a wider audience. Thus a [[http://etherboot.org/pipermail/gpxe-devel/2010-June/000345.html|call for feedback]] was sent to -devel.
