 * 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
 *        via CSR_EEPROM and CSR_OTP registers
