Xen ARM with Virtualization Extensions/Stout

This wiki describes how to run Xen on Renesas Stout board with R-Car H2 SoC.

Main information how to deal with Stout board are located at: https://elinux.org/R-Car/Boards/Yocto https://elinux.org/R-Car/Boards/Stout

Prepare U-boot

Get U-Boot sources

Clone sources from upstream and checkout on commit 425c0a43fbbec36571f6a03b530695b8b16a841d “Prepare v2019.01-rc3”:

git clone git://git.denx.de/u-boot.git
cd u-boot
git checkout 425c0a43fbbec36571f6a03b530695b8b16a841d -b stout_uboot

Apply additional patches

Apply the following patch series (PSCI support for r8a7790 SoC): https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg44364.html

Configure U-Boot

export CROSS_COMPILE=<path_to_gcc>
make stout_defconfig
make menuconfig

Set maximum supported CPUs for PSCI to 8:

    ARM architecture  --->
        [*] Enable support for booting in non-secure mode
            (8) Maximum supported CPUs for PSCI

Build U-Boot

make

Copy resulting images to tftp directory for the future flashing:

sudo cp u-boot.img <path_to_tftp_dir>/
sudo cp spl/u-boot-spl.bin <path_to_tftp_dir>/
