I have tried
3.7 kernel and
used 3.9-rc even. But i cannot built kenel correctly.Because
some files such as arm64/boot/dts/vexpress-v2p-aarch64.dts,vexpress-foundation-v8.dts,vexpress-v2m-rs1.dtsi,skeleton.dtsi and arm64/configs/vexpress_defconfig.So i cannot complete building kernel above.Also i cannot use boot wrapper to generate a linux-system-foundation.axf
suitable for a Foundation model.
>Same way as you build older one.
I have tried build arm64 kernel according to the steps of
BuildArm64Kernel(https://wiki.linaro.org/HowTo/BuildArm64Kernel).
But i encountered the problems above.So i need to ask for help to know how to build arm64 kernel and generate a linux-system-foundation.axf which can run on Foundation
model.For exmaple i should how to write configuration files such as vexpress_defconfig,vexpress-foundation-v8.dts,vexpress-v2p-aarch64.dts and so on.
