/* Outline: */
/* This header file defines operations for reading data from, and writing */
/* data to, target memory. */
/* */
/* The data transferred may be of any length, and its start address may */
/* have any alignment. */
/* */
/* These operations must be supplied with more basic operations which can */
/* read or write an arbitrary number of complete words of data to or from */
/* word-aligned addresses. */
/* */
/* Optionally, an operation which can write an arbitrary number of copies */
/* of a word-sized pattern to memory, starting at a word-aligned address, */
/* may be supplied for use by the arc_write_pattern operation; this is an */
/* optimisation for improving performance: if it is not supplied, the */
/* arc_write_pattern operation will use repeated calls of the supplied */
/* 'write_words' operation. */
/* */
/* A pointer to user-defined data may be passed to these operations: it */
/* will be passed to the basic operations when they are invoked (this */
/* allows any required context data to be passed to those operations). */
/* */
