[Xen-devel] [PATCH v7 00/12] arm: more kconfig configurability and small default configs

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

This patch series is the first step toward building a small certifiable
Xen hypervisor for ARM boards.

The series makes a few changes to allow disabling more kconfig options:
most of them already exist but cannot be disabled. It also introduces a
reference kconfig for Renesas RCar (due to popular demand, candidate for
certifications), Xilinx MPSoC, and for QEMU aarch64 (not for
certifications, but useful for debugging).

The last three patches clarify and make changes to the security support
status of kconfig options in Xen. We might want to merge them into
previous patches, or move them earlier in the series. I am happy to do
that once we settled on the required wording for SUPPORT.md.

Cheers,

Stefano

- improved wording of support statements
- remove SCHED_NULL from supported
