![]() When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

U-Boot for Amlogic P212 ======================= P212 is a reference board manufactured by Amlogic with the following specifications: - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz - ARM Mali 450 GPU - 2GB DDR3 SDRAM - 10/100 Ethernet - HDMI 2.0 4K/60Hz display - 2 x USB 2.0 Host - eMMC, microSD - Infrared receiver - SDIO WiFi Module - CVBS+Stereo Audio Jack Schematics are available from Amlogic on demand. Currently the u-boot port supports the following devices: - serial - eMMC, microSD u-boot compilation ================== > export ARCH=arm > export CROSS_COMPILE=aarch64-none-elf- > make p212_defconfig > make Image creation ============== Amlogic doesn't provide sources for the firmware and for tools needed to create the bootloader image, so it is necessary to obtain them from the git tree published by the board vendor: > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz > tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz > export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot > cd amlogic-u-boot > make gxl_p212_v1_defconfig > make > export FIPDIR=$PWD/fip Go back to mainline U-boot source tree then : > mkdir fip > cp $FIPDIR/gxl/bl2.bin fip/ > cp $FIPDIR/gxl/acs.bin fip/ > cp $FIPDIR/gxl/bl21.bin fip/ > cp $FIPDIR/gxl/bl30.bin fip/ > cp $FIPDIR/gxl/bl301.bin fip/ > cp $FIPDIR/gxl/bl31.img fip/ > cp u-boot.bin fip/bl33.bin > $FIPDIR/blx_fix.sh \ fip/bl30.bin \ fip/zero_tmp \ fip/bl30_zero.bin \ fip/bl301.bin \ fip/bl301_zero.bin \ fip/bl30_new.bin \ bl30 > $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0 > $FIPDIR/blx_fix.sh \ fip/bl2_acs.bin \ fip/zero_tmp \ fip/bl2_zero.bin \ fip/bl21.bin \ fip/bl21_zero.bin \ fip/bl2_new.bin \ bl2 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin > $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig > $FIPDIR/gxl/aml_encrypt_gxl --bootmk \ --output fip/u-boot.bin \ --bl2 fip/bl2.n.bin.sig \ --bl30 fip/bl30_new.bin.enc \ --bl31 fip/bl31.img.enc \ --bl33 fip/bl33.bin.enc and then write the image to SD with: > DEV=/dev/your_sd_device > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
