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. + +Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> +Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> +--- + drivers/misc/Kconfig | 12 ++++++++++++ + drivers/misc/Makefile | 1 + + 2 files changed, 13 insertions(+) + +--- a/drivers/misc/Kconfig ++++ b/drivers/misc/Kconfig +@@ -151,6 +151,18 @@ config SGI_IOC4 + If you have an SGI Altix with an IOC4-based card say Y. + Otherwise say N. + ++config OWL_LOADER ++ tristate "Owl loader for initializing Atheros PCI(e) Wifi chips" ++ depends on PCI ++ ---help--- ++ This kernel module helps to initialize certain Qualcomm ++ Atheros' PCI(e) Wifi chips, which have the init data ++ (which contains the PCI device ID for example) stored ++ together with the calibration data in the file system. ++ ++ This is necessary for devices like the Cisco Meraki Z1, say M. ++ Otherwise say N. ++ + config TIFM_CORE + tristate "TI Flash Media interface support" + depends on PCI +--- a/drivers/misc/Makefile ++++ b/drivers/misc/Makefile +@@ -13,6 +13,7 @@ obj-$(CONFIG_ATMEL_TCLIB) += atmel_tclib + obj-$(CONFIG_DUMMY_IRQ) += dummy-irq.o + obj-$(CONFIG_ICS932S401) += ics932s401.o + obj-$(CONFIG_LKDTM) += lkdtm.o ++obj-$(CONFIG_OWL_LOADER) += owl-loader.o + obj-$(CONFIG_TIFM_CORE) += tifm_core.o + obj-$(CONFIG_TIFM_7XX1) += tifm_7xx1.o + obj-$(CONFIG_PHANTOM) += phantom.o |
