53 * FreeCalypso change: the following hack is a band-aid fix
54 * for what appears to be a race condition bug that has always
55 * been present in TI's TCS211 fw. It appears that some parts
56 * of the fw can call etm_register() before ETM has initialized
57 * itself, and the call to etm_malloc() below results in a
58 * crash.
