3719e39c5baSBill Taylor 	 * Failsafe firmware programming ensures that an HCA device
3729e39c5baSBill Taylor 	 * can boot up in a functional mode even if the burn process
3739e39c5baSBill Taylor 	 * was interrupted (because of a power failure, reboot, user
3749e39c5baSBill Taylor 	 * interrupt, etc.). This can be implemented by burning the
3759e39c5baSBill Taylor 	 * new image to a vacant region on the Flash, and erasing the
3769e39c5baSBill Taylor 	 * old image only after the new image is successfully burnt.
3779e39c5baSBill Taylor 	 * This method ensures that there is at least one valid firmware
3789e39c5baSBill Taylor 	 * image on the Flash at all times. Thus, in case a firmware
3799e39c5baSBill Taylor 	 * image programming process is aborted for any reason, the HCA
3809e39c5baSBill Taylor 	 * will still be able to boot up properly using the valid image

3859e39c5baSBill Taylor 	 * Following are some general notes regarding the Flash memory
3869e39c5baSBill Taylor 	 * in the context of Mellanox HCA devices:
3879e39c5baSBill Taylor 	 * > The Flash memory is divided into sectors, and each sector
3889e39c5baSBill Taylor 	 *   must be erased prior to its programming.
3899e39c5baSBill Taylor 	 * > The image to be burnt is byte packed and should be programmed
3909e39c5baSBill Taylor 	 *   into the Flash byte by byte, preserving the byte order, starting
3919e39c5baSBill Taylor 	 *   at offset zero. No amendments are needed for endianess.
3929e39c5baSBill Taylor 	 * > It is recommended to program the Flash while the device is idle.
3939e39c5baSBill Taylor 	 * ===========================================================
3949e39c5baSBill Taylor 	 *
3959e39c5baSBill Taylor 	 * The comment about endianness is particularly important for us
3969e39c5baSBill Taylor 	 * since we operate on both big- and litte-endian hosts - it means
3979e39c5baSBill Taylor 	 * we have to do some byte-swapping gymnastics

4059e39c5baSBill Taylor 	 * This section provides an example of a programming utility
4069e39c5baSBill Taylor 	 * that performs a Failsafe firmware image update. The flow
4079e39c5baSBill Taylor 	 * ensures that there is at least one valid firmware image on
4089e39c5baSBill Taylor 	 * the Flash at all times. Thus, in case a firmware image pro-
4099e39c5baSBill Taylor 	 * gramming process is aborted for any reason, the HCA will

4119e39c5baSBill Taylor 	 * the Flash. Any other flow that ensures the above is also
4129e39c5baSBill Taylor 	 * considered a Failsafe firmware update.
4139e39c5baSBill Taylor 	 *
4149e39c5baSBill Taylor 	 * Update Flow:
4159e39c5baSBill Taylor 	 * * Check the validity of the PPS and SPS:
4169e39c5baSBill Taylor 	 * > If both PSs are valid, arbitrarily invalidate one of them
4179e39c5baSBill Taylor 	 * > If both PSs are invalid, the image on flash is corrupted
4189e39c5baSBill Taylor 	 *   and cannot be updated in a Failsafe way. The user must
4199e39c5baSBill Taylor 	 *   burn a full image in a non-failsafe way.
4209e39c5baSBill Taylor 	 *
4219e39c5baSBill Taylor 	 * > If only the PPS is valid:
4229e39c5baSBill Taylor 	 *   i.Burn the secondary image (erase each sector first)
4239e39c5baSBill Taylor 	 *  ii.Burn the SPS with the correct image address (FIA field)
