From 70db4212fcdb080444a23dccaf673b68a3ffc1fa Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 15 Feb 2012 15:51:16 -0800 Subject: sandbox: add getopt support This adds simple command-line parsing to sandbox. The idea is that it sets up the state with options provided, and this state can then be queried later, as needed. New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro, pointers are automatically gathered up in a special section, and then the core code takes care of gathering them up and processing at runtime. This way there is no central place where we have to store a list of flags with ifdefs.
