Earlier versions didn't need that as they where using an EEPROM for that purpose. This series takes care of setting up the relevant infrastructure and run the firmware loading routine at the right moment. Note that this builds on top of Sylwester Nawrocki's "USB host support for Raspberry Pi 4 board" series. --- Note: this was tested on both rpi_arm64_defconfig on both rpi3 & rpi4. Changes since v2: - Correct comment on patch #1 - Address Matthias' comments Changes since v1: - Rename function - Use callback in xhci-pci.c Nicolas Saenz Julienne (2): arm: rpi: Add function to trigger VL805's firmware load usb: xhci: Load Raspberry Pi 4 VL805's firmware arch/arm/mach-bcm283x/include/mach/mbox.h | 13 +++++++ arch/arm/mach-bcm283x/include/mach/msg.h | 7 ++++ arch/arm/mach-bcm283x/msg.c | 45 +++++++++++++++++++++++ board/raspberrypi/rpi/rpi.c | 6 +++ drivers/usb/host/xhci-pci.c | 6 +++ include/usb/xhci.h | 3 ++ 6 files changed, 80 insertions(+) -- 2.26.2
