/*
 * Override of CubeN6's usbd_conf.h.
 *
 * The stock OBL exposes 5 DFU alts (Flashlayout / FSBL-EXT / FSBL-APP /
 * <user app> / OTP) wired to the OBL middleware's phase machinery
 * (PHASE_FLASHLAYOUT / PHASE_3 / PHASE_4 / PHASE_CMD / PHASE_OTP). The
 * Betaflight OBL only needs a single memory descriptor — the BF slot at
 * 0x70100000 (or nor0 0x0 in recovery mode). Collapsing to one alt does
 * three things:
 *
 *   1. The host shows our @Betaflight memory descriptor as THE name on
 *      enumeration instead of "@Flashlayout /0x00/1*1Ke".
 *   2. dfu-util / STM32CubeProgrammer aim writes at alt 0 by default,
 *      no `-a 3` needed.
 *   3. We can bypass the OBL middleware's alt→phase logic and the
 *      OPENBL_USB_Download/EraseMemory phase-table machinery — those
 *      paths are wired for ST's signed-FSBL flow and silently no-op for
 *      a plain XIP user app at PHASE_CMD.
 *
 * Pulled in via the Makefile's `-I.` include path which precedes the
 * CubeN6 example's USB_Device/Target/.
