[Xen-devel] xen/arm: Bootwrapper update to support PSCI and GICv3

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello all,

I've been working on updating our aarch64 bootwrapper
to support new feature such as PSCI and GICv3.

Rather than porting the feature from the Linux bootwrapper [1].
I've added support of Xen on top of the Linux repo.

Below an example to configure bootwrapper with GICv3 and PSCI for
the foundation model:

42sh> ./configure --host=aarch64-linux-gnu              \
--with-kernel-dir=$HOME/linux-build/aarch64     \
--with-dtb=$HOME/arm-trusted-firmware/fdts/fvp-foundation-gicv3-psci.dtb \
--with-cmdline="console=hvc0 earlycon=pl011,0x1c090000 init=/root/init.sh 
root=/dev/vda" \
--enable-psci --with-xen-cmdline="dtuart=serial0 console=dtuart no-bootscrub"   
         \
--with-xen="$HOME/xen" --enable-gicv3
42sh> make

Make will produce a xen-system.axf which is the image used to boot
Xen on the model.

The branch with the new version is:
git://xenbits.xen.org/people/julieng/boot-wrapper-aarch64.git branch xen

Ian, can you update your repo with this new version?

Regards,
