[Qemu-devel] [RFC PATCH 0/3] pflash_cfi01: allow reading/writing it only in secure mode

[Paolo Bonzini <pbonzini@redhat.com>]

This is an example of usage of attributes in a device model.  It lets
you block flash writes unless the CPU is in secure mode.  Enabling it
currently requires a -readconfig file:

        [global]
        driver = "cfi.pflash01"
        property = "secure"
        value = "on"

because the driver includes a "."; however, I plan to enable this through
the command line for the final version of the patches.

In the meanwhile, a review of the approach and of the actual memattrs bit
would be great.
