    Whitelist exported platform properties · e4971454
    Jaekyun Seok authored
    This CL lists all the exported platform properties in
    private/exported_property_contexts.
    
    Additionally accessing core_property_type from vendor components is
    restricted.
    Instead public_readable_property_type is used to allow vendor components
    to read exported platform properties, and accessibility from
    vendor_init is also specified explicitly.
    
    Note that whitelisting would be applied only if
    PRODUCT_COMPATIBLE_PROPERTY is set on.
    
    Bug: 38146102
    Test: tested on walleye with PRODUCT_COMPATIBLE_PROPERTY=true
    Change-Id: I304ba428cc4ca82668fec2ddeb17c971e7ec065e
