310 * il4965_load_bsm - Load bootstrap instructions
311 *
312 * BSM operation:
313 *
314 * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
315 * in special SRAM that does not power down during RFKILL. When powering back
316 * up after power-saving sleeps (or during initial uCode load), the BSM loads
317 * the bootstrap program into the on-board processor, and starts it.
318 *
319 * The bootstrap program loads (via DMA) instructions and data for a new
320 * program from host DRAM locations indicated by the host driver in the
321 * BSM_DRAM_* registers. Once the new program is loaded, it starts
322 * automatically.
323 *
324 * When initializing the NIC, the host driver points the BSM to the
325 * "initialize" uCode image. This uCode sets up some internal data, then
326 * notifies host via "initialize alive" that it is complete.
327 *
328 * The host then replaces the BSM_DRAM_* pointer values to point to the
329 * normal runtime uCode instructions and a backup uCode data cache buffer
330 * (filled initially with starting data values for the on-board processor),
331 * then triggers the "initialize" uCode to load and launch the runtime uCode,
332 * which begins normal operation.
333 *
334 * When doing a power-save shutdown, runtime uCode saves data SRAM into
335 * the backup data cache in DRAM before SRAM is powered down.
336 *
337 * When powering back up, the BSM loads the bootstrap program. This reloads
338 * the runtime uCode instructions and the backup data cache into SRAM,
339 * and re-launches the runtime uCode from where it left off.
