  289. * UCODE-DRIVER GP (general purpose) mailbox register 1

  292. * Bit fields:
  293. * 4: UCODE_DISABLE
  294. * Host sets this to request permanent halt of uCode, same as
  295. * sending CARD_STATE command with "halt" bit set.
  296. * 3: CT_KILL_EXIT
  297. * Host sets this to request exit from CT_KILL state, i.e. host thinks
  298. * device temperature is low enough to continue normal operation.
  299. * 2: CMD_BLOCKED
  300. * Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
  301. * to release uCode to clear all Tx and command queues, enter
  302. * unassociated mode, and power down.
  303. * NOTE: Some devices also use HBUS_TARG_MBX_C register for this bit.
  304. * 1: SW_BIT_RFKILL
  305. * Host sets this when issuing CARD_STATE command to request
  306. * device sleep.
  307. * 0: MAC_SLEEP
  308. * uCode sets this when preparing a power-saving power-down.
  309. * uCode resets this when power-up is complete and SRAM is sane.
  310. * NOTE: device saves internal SRAM data to host when powering down,
  311. * and must restore this data after powering back up.
  312. * MAC_SLEEP is the best indication that restore is complete.
  313. * Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
  314. * do not need to save/restore it.
