Peter Maydell b2962f4613 memory: Define API for MemoryRegionOps to take attrs and return status ... Define an API so that devices can register MemoryRegionOps whose read and write callback functions are passed an arbitrary pointer to some transaction attributes and can return a success-or-failure status code. This will allow us to model devices which: * behave differently for ARM Secure/NonSecure memory accesses * behave differently for privileged/unprivileged accesses * may return a transaction failure (causing a guest exception) for erroneous accesses This patch defines the new API and plumbs the attributes parameter through to the memory.c public level functions io_mem_read() and io_mem_write(), where it is currently dummied out. The success/failure response indication is also propagated out to io_mem_read() and io_mem_write(), which retain the old-style boolean true-for-error return.
