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