* iwl4965_load_bsm - Load bootstrap instructions

103
* up after power-saving sleeps (or during initial uCode load), the BSM loads
104
* the bootstrap program into the on-board processor, and starts it.
106

107
* program from host DRAM locations indicated by the host driver in the
108
* BSM_DRAM_* registers. Once the new program is loaded, it starts
111
* When initializing the NIC, the host driver points the BSM to the
112
* "initialize" uCode image. This uCode sets up some internal data, then
113
* notifies host via "initialize alive" that it is complete.
115
* The host then replaces the BSM_DRAM_* pointer values to point to the
116
* normal runtime uCode instructions and a backup uCode data cache buffer
117
* (filled initially with starting data values for the on-board processor),
118
* then triggers the "initialize" uCode to load and launch the runtime uCode,
119
* which begins normal operation.
121
* When doing a power-save shutdown, runtime uCode saves data SRAM into
122
* the backup data cache in DRAM before SRAM is powered down.
124
* When powering back up, the BSM loads the bootstrap program. This reloads
125
* the runtime uCode instructions and the backup data cache into SRAM,
126
* and re-launches the runtime uCode from where it left off.
