* CSR ( control and status registers )

* CSR registers are mapped directly into PCI bus space , and are accessible
* whenever platform supplies power to device , even when device is in
* low power states due to driver - invoked device resets
* ( e . g . CSR_RESET_REG_FLAG_SW_RESET ) or uCode - driven power - saving modes .
*
* Use iwl_write32 ( ) and iwl_read32 ( ) family to access these registers ;
* these provide simple PCI bus access , without waking up the MAC .
* Do not use iwl_write_direct32 ( ) family for these registers ;
* no need to " grab nic access " via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ .
* The MAC ( uCode processor , etc . ) does not need to be powered up for accessing
* the CSR registers .

* NOTE : Device does need to be awake in order to read this memory
