Subject: [PATCH v3 0/4] platform/chrome: vboot context support

Hi everyone,

This series adds support for reading and writing the verified boot context
nvram space on the EC using the cros_ec sysfs interface.

The first patch improves is_visible() functionality, making it work
for binary attributes as well as normal ones. This is needed so the
sysfs group can be hidden when the EC doesn't offer any space for
the context.

The second patch documents the property used in the binding documents.
This used to live in the next patch on the previous versions of this series.

The third patch is the actual code implementing the interface to read
and write the context data.

The fourth patch adds the DT properties on peach boards which, judging by
the vendor tree, use the EC to store the verified boot context.

The series was tested on a peach pi and was found to work OK there. As
always, all comments and further tests are welcome :)

Cheers!
Emilio
