#     powerpc: signedness bug in update_flash_db()
#     
#     The "count < sizeof(struct os_area_db)" comparison is type promoted to
#     size_t so negative values of "count" are treated as very high values and
#     we accidentally return success instead of a negative error code.
#     
#     This doesn't really change runtime much but it fixes a static checker
#     warning.
