1Marvell U-Boot Build Instructions
2=================================
3
4This document describes how to compile the U-Boot and how to change U-Boot configuration
5
6Build Procedure
7----------------
81. 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
142. Set the cross compiler:
15
16		# export CROSS_COMPILE=/path/to/toolchain/aarch64-marvell-linux-gnu-
17
183. Clean-up old residuals:
19
20		# make mrproper
21
224. 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
315. 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.

50Configuration update

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