Initial commit for the firmware. Used the 20090306_ela version as baseline.

It is identical to the popular 20081211, with the doob addition (20090301), a
linux client, and two additional commands for LF analysis. Let me know if
you find issues here!

+This is a bare minimum compile environment for the proxmark3 sources. 
+
+CONTENTS
+
+This bundle contains the ARM cross compiler in devkitARM and a _tiny_ subset
+of the Visual C++ 2008 Express Edition in devkitWIN which is the bare minimum
+required for compilation of this current source.
+
+If you plan on further source code development you are strongly encouraged
+to download the full Visual C++ 2008 available for free download from
+http://www.microsoft.com/express/download/
+
+CAVEATS
+
+There is no provision in this environment for compiling the FPGA source. To
+do that you need to download the free (registration required) ISE WebPack
+from Xilinx at http://www.xilinx.com/ise/logic_design_prod/webpack.htm
+Be warned, the pack is huge, 2Gb download and >4Gb installed.
+
+USAGE
+
+First of all run the .msi file in devkitWIN\vcredist_x86 to install the VC++
+redistributables, without these, nmake, cl and link won't run.
+
+Get a command prompts in the cockpit directory and pretty much run the batch
+files in the order they appear:
+
+0setpath.bat  - sets the environment vars for the compile environment
+1makearm.bat  - compiles the files in armsrc, output files in armsrc\obj
+2makeboot.bat - compiles the files in bootrom, output files in bootrom\obj
+3makewin.bat  - compiles the files in winsrc, output files in winsrc\obj
+4flashos.bat  - attempts to upload the OS image to the proxmark3 board
