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.
