fc-iram: added '+' to getopt magic string like in fc-xram Both fc-iram and fc-xram now support secondary program invokation. If the user needs to pass some options to the secondary program, we don't want fc-iram or fc-xram to claim these options as its own, thus we need to stop getopt() from reordering arguments. This fix was already implemented in fc-xram a long time ago, but the issue was overlooked when secondary program invokation ability was added to fc-iram.

/*
 * In some error cases in our loadagent code we have no better course
 * of action available than to halt in a tight loop.  We define _exit()
 * to do the latter.  We have defined some codes for the argument value
 * that goes into R0; if you manage to hook up JTAG and get it to work,
 * you might be able to see what went wrong.
