+ * BSM operation:

+ * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
+ * in special SRAM that does not power down during RFKILL.  When powering back
+ * up after power-saving sleeps (or during initial uCode load), the BSM loads
+ * the bootstrap program into the on-board processor, and starts it.
+ *
+ * The bootstrap program loads (via DMA) instructions and data for a new
+ * program from host DRAM locations indicated by the host driver in the
+ * BSM_DRAM_* registers.  Once the new program is loaded, it starts
+ * automatically.
+ *
+ * When initializing the NIC, the host driver points the BSM to the
+ * "initialize" uCode image.  This uCode sets up some internal data, then
+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.
+ *
+ * When powering back up, the BSM loads the bootstrap program.  This reloads
+ * the runtime uCode instructions and the backup data cache into SRAM,
+ * and re-launches the runtime uCode from where it left off.

- *
- * BSM operation:
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down during RFKILL.  When powering back
- * up after power-saving sleeps (or during initial uCode load), the BSM loads
- * the bootstrap program into the on-board processor, and starts it.
- *
- * The bootstrap program loads (via DMA) instructions and data for a new
- * program from host DRAM locations indicated by the host driver in the
- * BSM_DRAM_* registers.  Once the new program is loaded, it starts
- * automatically.
- *
- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image.  This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program.  This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
- * and re-launches the runtime uCode from where it left off.
