MMIO Operations MMIO Operations
--------------- ---------------
MMIO regions are provided with ->read() and ->write() callbacks; in addition MMIO regions are provided with ->read() and ->write() callbacks,
various constraints can be supplied to control how these callbacks are called: which are sufficient for most devices. Some devices change behaviour
based on the attributes used for the memory transaction, or need
to be able to respond that the access should provoke a bus error
rather than completing successfully; those devices can use the
->read_with_attrs() and ->write_with_attrs() callbacks instead.
In addition various constraints can be supplied to control how these
callbacks are called:
- .valid.min_access_size, .valid.max_access_size define the access sizes - .valid.min_access_size, .valid.max_access_size define the access sizes
(in bytes) which the device accepts; accesses outside this range will (in bytes) which the device accepts; accesses outside this range will
