      ARM: add Raspberry Pi 3 64-bit config · d22a7657
      Stephen Warren authored
      On all Pis so far, the VC FW provides a short stub to set up the ARM CPU
      before entering the kernel (a/k/a U-Boot for us). This feature is not
      currently supported by the VC FW when booting in 64-bit mode. However,
      this feature will likely appear in the near future, and this U-Boot port
      assumes that such a feature is in place. Without that feature, or a
      temporary workaround described below, U-Boot will not boot.
      
      Once the VC FW does provide the ARM stub, u-boot.bin built for rpi_3 can
      be used drectly as kernel7.img, in the same way as any other RPi port. The
      following config.txt is required:
      
          # Fix mini UART input frequency, and setup/enable up the UART.
          # Without this option, U-Boot will not boot, even if you don't care
          # about the serial console. This option will always be required for
          # all RPi3 use-cases, unless the PL011 UART is used, which is not
          # yet supported by rpi_3* builds of U-Boot.
          enable_uart=1
          # Boot in AArch64 (64-bit) mode.
          # It is possible that a future VC FW will remove the need for this
          # option, instead auto-setting 32-/64-bit mode based on the "kernel"
          # filename present on the SD card.
          arm_control=0x200
      
      Prior to the VC FW providing the ARM boot stub, you can use the following
      steps to build an equivalent stub into the U-Boot binary:
      
      git clone https://github.com/swarren/rpi-3-aarch64-demo.git \
          ../rpi-3-aarch64-demo
      (cd ../rpi-3-aarch64-demo && ./build.sh)
      Build U-Boot for rpi_3 in the usual way
      cat ../rpi-3-aarch64-demo/armstub64.bin u-boot.bin > u-boot.bin.stubbed
      Use u-boot.bin.stubbed as kernel7.img on the Pi SD card.
      
      In this case, the following additional entries are required in config.txt:
      
          # Tell the FW to load the kernel image at address 0, the reset vector.
          kernel_old=1

      arm: socfpga: sr1500: Remove USB_GADGET · 4861be7e
      Sam Protsenko authored
      "buildman" tool revealed that USB_GADGET was enabled by mistake for this
      board in process of moving that option to Kconfig. Remove it to bring
      things back to correct state.
