Issue building SIMtrace firmware from OpenPCD repository

Hello, I'm unable to build the SIMtrace firmware according to the instructions on the wiki at http://bb.osmocom.org/trac/wiki/SIMtrace/Firmware. The GCC 4.5.2 ARM cross compiler has been installed and added to my path. Here is the output when I run make: ~/repos/openpcd/firmware$ make -f Makefile.dfu BOARD=SIMTRACE -------- begin (mode: RUN_FROM_ROM) -------- arm-elf-gcc (GCC) 4.5.2 Copyright (C) 2010 Free Software Foundation, Inc.

Looking through Makefile and Makefile.dfu, I don't see any references to the project. None of the checks on the $BOARD variable include a SIMTRACE option. Similarly, Cstartup.S only defines PIO_BOOTLDR for PCD, PICC, and OLIMEX boards. I'm still browsing through some other source files to see if I'm missing something obvious, but I'd appreciate any advice. Thanks, -Nick P.
