   4 Subject: misc: owl-loader for delayed Atheros ath9k fixup
   5
   6 Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
   7 need to be able to initialize the PCIe wifi device. Normally, this is done
   8 during the early stages of booting linux, because the necessary init code
   9 is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
  10 However,this isn't possible for devices which have the init code for the
  11 Atheros chip stored on NAND in an UBI volume. Hence, this module can be
  12 used to initialze the chip when the user-space is ready to extract the
  13 init code.
