   1 Marvell U-Boot Build Instructions
   2 =================================
   3
   4 This document describes how to compile the U-Boot and how to change U-Boot configuration
   5
   6 Build Procedure
   7 ----------------
   8 1. Install required packages:
   9
  10                 # sudo apt-get install libssl-dev
  11                 # sudo apt-get install device-tree-compiler
  12                 # sudo apt-get install swig libpython-dev
  13
  14 2. Set the cross compiler:
  15
  16                 # export CROSS_COMPILE=/path/to/toolchain/aarch64-marvell-linux-gnu-
  17
  18 3. Clean-up old residuals:
  19
  20                 # make mrproper
  21
  22 4. Configure the U-Boot:
  23
  24                 # make <defconfig_file>
  25
  26         - For the Armada-70x0/80x0 DB board use "mvebu_db_armada8k_defconfig"
  27         - For the Armada-80x0 MacchiatoBin use "make mvebu_mcbin-88f8040_defconfig"
  28         - For the Armada-3700 DB board use "make mvebu_db-88f3720_defconfig"
  29         - For the Armada-3700 EsspressoBin use "make mvebu_espressobin-88f3720_defconfig"
  30
  31 5. Configure the device-tree and build the U-Boot image:
  32
  33         Compile u-boot and set the required device-tree using:
  34
  35                 # make DEVICE_TREE=<name>
  36
  37         NOTE:
  38         Compilation with "mvebu_db_armada8k_defconfig" requires explicitly exporting DEVICE_TREE
  39         for the requested board.
  40         By default, u-boot is compiled with armada-8040-db device-tree.
  41         Using A80x0 device-tree on A70x0 might break the device.
  42         In order to prevent this, the required device-tree MUST be set during compilation.
  43         All device-tree files are located in ./arch/arm/dts/ folder.
  44
  45         NOTE:
  46         The u-boot.bin should not be used as a stand-alone image.
  47         The ARM Trusted Firmware (ATF) build process uses this image to generate the
  48         flash image.

  50 Configuration update
  51 ---------------------
  52         To update the U-Boot configuration, please refer to doc/README.kconfig
