- * These macros are intended for use when there is a need to copy a low-level
- * function body into special memory.
- *
- * For example, when reconfiguring the SDRAM controller, the code doing the
- * reconfiguration may need to run from SRAM.
- *
- * NOTE: that the copied function body must be entirely self-contained and
- * position-independent in order for this to work properly.
- *
- * NOTE: in order for embedded literals and data to get referenced correctly,
- * the alignment of functions must be preserved when copying.  To ensure this,
- * the source and destination addresses for fncpy() must be aligned to a
- * multiple of 8 bytes: you will be get a BUG() if this condition is not met.
- * You will typically need a ".align 3" directive in the assembler where the
- * function to be copied is defined, and ensure that your allocator for the
- * destination buffer returns 8-byte-aligned pointers.
- *
- * Typical usage example:
- *
- * extern int f(args);
- * extern uint32_t size_of_f;
- * int (*copied_f)(args);
- * void *sram_buffer;
- *
- * copied_f = fncpy(sram_buffer, &f, size_of_f);
- *
- * ... later, call the function: ...
- *
- * copied_f(args);
- *
- * The size of the function to be copied can't be determined from C:
- * this must be determined by other means, such as adding assmbler directives
- * in the file where f is defined.
