The buffer manager module is used to allocate buffers to hold boot data. The MCU code allocates a buffer when it is ready to read a block of data from the boot peripheral. Once the data is read the buffer ownership is passed to the SMS. When the SMS has completed processing the data in the buffer ownership is returned to the MCU, which then frees the buffer.
