+==============
+
+This layer provides that evaluation board is mounted ARM SoCs of Renesas
+Electronics, called the R-Car Generation 3. Currently, this supports
+board and the SoCs of the following:
+ - Board: Salvator-X / SoC: R8A7795 (R-Car H3), R8A7796 (R-Car M3)
+ - Board: R-Car Starter Kit premier(H3ULCB) / SoC: R8A7795
+
+Patches
+=======
+
+Please submit any patches for this layer to: takamitsu.honda.pv@renesas.com
+Please see the MAINTAINERS file for more details.
+
+Dependencies
+============
+
+This layer depends on:
+
+ URI: git://git.yoctoproject.org/poky
+ layers: meta, meta-yocto, meta-yocto-bsp
+ branch: krogoth
+
+ URI: git://git.yoctoproject.org/meta-renesas
+ layers: meta-rcar-gen3
+ branch: krogoth
+
+ URI: https://git.linaro.org/openembedded/meta-linaro.git
+ layers: meta-linaro-toolchain
+ branch: krogoth
+
+ URI: git://git.openembedded.org/meta-openembedded
+ layers: meta-oe
+ branch: krogoth
+
+Build Instructions
+==================
+
+The following instructions require a Poky installation (or equivalent).
+
+Initialize a build using the 'oe-init-build-env' script in Poky. e.g.:
+
+ $ source poky/oe-init-build-env
+
+After that, initialized configure bblayers.conf by adding meta-rcar-gen3 layer. e.g.:
+
+ BBLAYERS ?= " \
+ <path to layer>/poky/meta \
+ <path to layer>/poky/meta-yocto \
+ <path to layer>/poky/meta-yocto-bsp \
+ <path to layer>/meta-renesas/meta-rcar-gen3 \
+ <path to layer>/meta-linaro/meta-linaro-toolchain \
+ <path to layer>/meta-openembedded/meta-oe \
+ "
+
+To build a specific target BSP, configure the associated machine in local.conf:
+
+ MACHINE ??= "<supported board name>"
+
+Select the SOC
+
+ For H3: r8a7795
+ SOC_FAMILY = "r8a7795"
+
+ For M3: r8a7796
+ SOC_FAMILY = "r8a7796"
+
+Must change the package class to ipk files in local.conf:
+
+ PACKAGE_CLASSES ?= "package_ipk"
+
+Must Change the Gcc version in local.conf.
+
+ GCCVERSION="linaro-5.2"
+
+Configure for systemd init in local.conf:
+
+ DISTRO_FEATURES_append = " systemd"
+ VIRTUAL-RUNTIME_init_manager = "systemd"
+
+Build the target file system image using bitbake:
+
+ $ bitbake core-image-minimal
+
+After completing the images for the target machine will be available in the output
+directory 'tmp/deploy/images/<supported board name>'.
+
+Images generated:
+ * Image (generic Linux Kernel binary image file)
+ * Image-<machine name>.dtb (DTB for target machine)
+ * core-image-minimal-<machine name>.tar.bz2 (rootfs tar+bzip2)
+ * core-image-minimal-<machine name>.ext4 (rootfs ext4 format)
+ * core-image-minimal-<machine name>.cpio.gz (rootfs cpio+gz format)
+
+Build Instructions for SDK
+==========================
+This may be changed in the near feature. These instructions are tentative.
+
+Should define the staticdev in SDK image feature for installing the static libs
+to SDK in local.conf.
+
+ SDKIMAGE_FEATURES_append = " staticdev-pkgs"
+
+Use bitbake -c populate_sdk for generating the toolchain SDK:
+For 64-bit target SDK (aarch64):
+
+ $ bitbake core-image-minimal -c populate_sdk
+
+The SDK can be found in the output directory 'tmp/deploy/sdk'
+ * poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
+
+Usage of toolchain SDK:
+Install the SDK to the default: /opt/poky/x.x
+(x.x is YP version, i.e. 2.1.)
+For 64-bit target SDK:
+
+ $ sh poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
+
+For 64-bit application use environment script in /opt/poky/x.x
+
+ $ source /opt/poky/x.x/environment-setup-aarch64-poky-linux
