kernel: 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. Martin Blumenstingl made a few fixes and added support for lantiq: kernel: owl-loader: add support for OWL emulation PCI devices kernel: owl-loader: don't re-scan the bus when ath9k_pci_fixup failed kernel: owl-loader: use dev_* instead of pr_* logging functions kernel: owl-loader: auto-generate the eeprom filename as fallback kernel: owl-loader: add a debug message when swapping the eeprom data kernel: owl-loader: add missing newlines in log messages kernel: owl-loader: add support for the lantiq platform These patches have been integrated.
