Purpose : Implementation of SEGGER real-time transfer (RTT) which
allows real-time communication on targets which support
debugger memory accesses while the CPU is running.

* RTT memcpy configuration
*
* memcpy() is good for large amounts of data,
* but the overhead is big for small amounts, which are usually stored via RTT.
* With SEGGER_RTT_MEMCPY_USE_BYTELOOP a simple byte loop can be used instead.
*
* SEGGER_RTT_MEMCPY() can be used to replace standard memcpy() in RTT functions.
* This is may be required with memory access restrictions,
* such as on Cortex-A devices with MMU.
