+= Malibu Board Support Package (BSP)
+Gateworks provides a Board Support Package (BSP) for the Malibu product family which provides source code and an easy mechanism to build different images.
+
+The Gateworks BSP is the easiest comprehensive software process because it contains everything. If a deep dive, expert path is desired, each piece of the BSP (boot firmware, rootfs, kernel) can all be built separately using the bsp Makefile as a guide.
+
+
+[=#images]
+== BSP Pre-Built Firmware Images
+
+Pre-built firmware images can be found on http://dev.gateworks.com/malibu/images.
+
+Installation instructions:
+ - [wiki:/malibu/firmware Malibu Flashing Instructions for updating from U-Boot or Linux]
+ - [wiki:jtag_instructions JTAG instructions for updating Boot Firmware]
+
+
+[=#source]
+== BSP Source Code
+Source code for the firmware, bootloader and kernel are hosted at !GitHub. We highly recommend you create a !GitHub account and 'Watch' these repositories to keep abreast of important feature additions, bugfixes, and firmware-releases. You can configure your !GitHub account to e-mail you when changes are made to repositories [https://github.com/settings/notifications here].
+
+The following !GitHub repos are used for Malibu:
+ * [https://github.com/Gateworks/bsp-malibu bsp-malibu] - Malibu BSP support scripts and Makefile  ([https://github.com/Gateworks/bsp-malibu/subscription watch])
+ * [https://github.com/Gateworks/atf-malibu atf-malibu] - ARM Trusted Firmware ([https://github.com/Gateworks/atf-malibu/subscription watch)]
+ * [https://github.com/Gateworks/mv_ddr-malibu mv_ddr-malibu] - Marvell DDR configuration 
+ ([https://github.com/Gateworks/mv_ddr-malibu/subscription watch)]
+ * [https://github.com/Gateworks/uboot-malibu uboot-malibu] - Malibu Bootloader ([https://github.com/Gateworks/uboot-malibu/subscription watch)]
+ * [https://github.com/Gateworks/linux-malibu linux-malibu] - Malibu Linux Kernel ([https://github.com/Gateworks/linux-malibu/subscription watch)]
+
+
+[=#build]
+== Building the BSP from source
+Below are instructions for building the entire BSP, which includes all of the bootloader components, Linux kernel, and Ubuntu.  Pre-built images are available [#images above].
+
+The following pre-requisites are needed to build the Malibu BSP:
+ * Linux Development host (desktop or laptop computer) (Ubuntu is used by Gateworks and tested)
+ * Git (used for source code repositories)
+
+Installing pre-requisites:
+{{{#!bash
+# install packages
+sudo apt update
+sudo apt install build-essential git
+sudo apt install wget bison flex libssl-dev libncurses-dev bc ncurses-dev liblzo2-dev lzop cpio rsync e2tools fdisk
+sudo apt install gcc-aarch64-linux-gnu
+# configure git
+git config --global user.email "you@example.com"
+git config --global user.name "Your Name"
+git config --global color.ui true
+}}}
+
+To obtain the code:
+ 1. Clone repo (fetch the repo manifest) '''Note the --recurse-submodules option which instructs git to pull the submodules'''
+
+{{{#!bash
+git clone --recurse-submodules https://github.com/Gateworks/bsp-malibu.git
+cd bsp-malibu
+}}}
+ 1. Setup build environment (***repeat this each time you open a shell***)
+{{{#!bash
+source setup-environment
+}}}
+ 1. Build desired software target as defined below. For example:
+{{{#!bash
+make -j8 ubuntu-image
+}}}
+
+The following build targets are useful:
+ - firmware-image: builds boot firmware:
+  * firmware-malibu-gw8901-jtag.bin - JTAG image
+  * firmware-malibu-gw8901.bin - for updating boot firmware only (no U-Boot env) from Linux/U-Boot
+  * firmware-malibu-gw8901.img - for updating boot firmware and U-Boot env from Linux/U-Boot
+  * malibu.env.bin - U-Boot environment
+ - kernel_image: builds linux-malibu.tar.xz kernel tarball containing modules and boot dir with kernel/dtb/script
+ - jammy-malibu.ext4: builds ext4 filesystem containing ubuntu rootfs plus gateworks kernel
+ - ubuntu-image: builds ubuntu disk image including partition table and ext4 fs
+
+
+[=#kernel]
+=== Modifying the stand-alone Linux Kernel
+The Gateworks Malibu BSP instructions [#build above] create an environment for building the Linux kernel among other targets.
+
+Some additional instructions for common actions (make sure you have already installed the BSP and setup your shell environment as specified above):
+ * Make standard Gateworks Malibu kernel with Gateworks malibu_linux_defconfig
+{{{#!bash
+make linux # first build the kernel with the standard malibu_linux_defconfig
+}}}
+ * Modify Kernel configuration (enabling modules etc):
+{{{#!bash
+make -C linux menuconfig # make your changes
+make -C linux savedefconfig # create a minimal 'defconfig' file in the linux kernel dir
+diff linux/defconfig linux/arch/arm64/configs/malibu_linux_defconfig # show diffs (optional)
+cp linux/defconfig linux/arch/arm64/configs/malibu_linux_defconfig . # copy the modified defconfig
+}}}
+ * Build kernel tarball:
+{{{#!bash
+make uboot # builds uboot, a requirement to build the kernel and modules and tarball
+make kernel_image # builds the kernel and modules and tarball
+}}}
+ * Build new disk image using the updated kernel tarball:
+{{{#!bash
+make ubuntu-image
+}}}
