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. |
