Re: [Xen-devel] [PATCH v5 0/10] arm: more kconfig configurability and small default configs

Hi all,

Hi,

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

First, the series makes a few changes to allow disabling more kconfig
options: most of them already exist but cannot be disabled.

Then, it 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 patch in the series adds a convenient cloc target to count the
total lines of code of the source files built.

As a consequence of these changes, some options will become user-visible
and not dependent on CONFIG_EXPERT. It does not mean that Xen Project
will security support all possible combinations of kconfig options.
Instead, there will be a small set of pre-canned configurations that
will be supported.  See: https://marc.info/?l=xen-devel&m=152424389512432

Cheers,

Stefano
