Hi Catalin,
Should I expect vanilla mainline (v3.14-rc7) to work with the current
aarch64 foundation model r0p0 (model build 0.8.5206)? I'm also using
the master branch of your boot-wrapper-aarch64 configured to point at
the mainline tree.
I've gotten as far as adding initcall_debug to the cmdline and noticing
that arm64_device_init never returns, but have to call it a day so have
to wait til tomorrow to debug further. In the mean time wanted to check
with you on whether it should work.
Thanks,
Kevin

This is not due to any kernel bug, but due to bootwrapper picking up wrong
device tree. I will work on fixing it in the boot-wrapper-aarch64 repo.
Meanwhile could change KERN_DTB in configure.ac to point to foundation-v8.dtb
and give it a try.
Regards,
Sudeep

Yup, that works. Now the kernel is getting all the way to userspace.
Thanks.
