The (eventually) upcoming ath(4) changes will include being able to load ath(4) devices on the AHB bus (ie the on-die wifi part of the SoC) as modules. In order for this to happen, a copy of the calibration data needs to be copied away before the SPI driver runs or the memory map access hack won't work. Now, ideally (!) there'd be some driver that can come up after the MTD pieces (eg, SPI, NAND, etc) and load into a firmware chunk the calibration data. (Or, really really nicely, would be an actual async firmware API that would lead itself to having a driver schedule a file read - or a raw device read - to get to the calibration data.) Now, until all of the above is done - I'm going to perpetuate the layer breaking atrocity here by simply doing the PCI bus fixup EEPROM/calibration data hack here. This will work for any AR71xx (and later on, AR231x/AR531x) device, as well as the handful of QCA MIPS + QCA9880v2 802.11ac boards with NOR flash. To use, this goes into the kernel config: # Enable EEPROM hacks options AR71XX_ATH_EEPROM device ar71xx_caldata device firmware # This enables the ath_ahb driver (when I commit the change!) to # pull data out of the firmware hack. options ATH_EEPROM_FIRMWARE In the hints file: # ART calibration data mapping device hint.ar71xx_caldata.0.at="nexus0" hint.ar71xx_caldata.0.order=0 # Where the ART is - last 64k in the first 8MB of flash hint.ar71xx_caldata.0.map.0.ath_fixup_addr=0x1fff0000 hint.ar71xx_caldata.0.map.0.ath_fixup_size=16384 # And now tell the ath(4) driver where to look! hint.ath.0.eeprom_firmware="ar71xx_caldata.0.map.0.eeprom_firmware" Tested: * carambola2, AR933x SoC, using a set of ath and ath_hal modules to load TODO: * unify this bit of firmware loading code, as I will definitely need to include both the PCI bus firmware version (for PCI ID fixups too!) as well as AHB/on-chip calibration data. * Commit the ath_ahb bus code * Convert .. everything over. That'll take the majority of the time.
