158 * The bootstrap program loads (via DMA) instructions and data for a new
159 * program from host DRAM locations indicated by the host driver in the
160 * BSM_DRAM_* registers. Once the new program is loaded, it starts
161 * automatically.
162 *
163 * When initializing the NIC, the host driver points the BSM to the
164 * "initialize" uCode image. This uCode sets up some internal data, then
165 * notifies host via "initialize alive" that it is complete.
166 *
167 * The host then replaces the BSM_DRAM_* pointer values to point to the
168 * normal runtime uCode instructions and a backup uCode data cache buffer
169 * (filled initially with starting data values for the on-board processor),
170 * then triggers the "initialize" uCode to load and launch the runtime uCode,
171 * which begins normal operation.
172 *
173 * When doing a power-save shutdown, runtime uCode saves data SRAM into
174 * the backup data cache in DRAM before SRAM is powered down.
175 *
176 * When powering back up, the BSM loads the bootstrap program. This reloads
177 * the runtime uCode instructions and the backup data cache into SRAM,
178 * and re-launches the runtime uCode from where it left off.

5213 * BSM operation:
5214 *
5215 * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
5216 * in special SRAM that does not power down during RFKILL. When powering back
5217 * up after power-saving sleeps (or during initial uCode load), the BSM loads
5218 * the bootstrap program into the on-board processor, and starts it.
5219 *
5220 * The bootstrap program loads (via DMA) instructions and data for a new
5221 * program from host DRAM locations indicated by the host driver in the
5222 * BSM_DRAM_* registers. Once the new program is loaded, it starts
5223 * automatically.
5224 *
5225 * When initializing the NIC, the host driver points the BSM to the
5226 * "initialize" uCode image. This uCode sets up some internal data, then
5227 * notifies host via "initialize alive" that it is complete.
5228 *
5229 * The host then replaces the BSM_DRAM_* pointer values to point to the
5230 * normal runtime uCode instructions and a backup uCode data cache buffer
5231 * (filled initially with starting data values for the on-board processor),
5232 * then triggers the "initialize" uCode to load and launch the runtime uCode,
5233 * which begins normal operation.
5234 *
5235 * When doing a power-save shutdown, runtime uCode saves data SRAM into
5236 * the backup data cache in DRAM before SRAM is powered down.
5237 *
5238 * When powering back up, the BSM loads the bootstrap program. This reloads
5239 * the runtime uCode instructions and the backup data cache into SRAM,
5240 * and re-launches the runtime uCode from where it left off.
