The buffer manager module is used to allocate buffers to hold boot data. The R5 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 M4. When the M4 has completed processing the data in the buffer ownership is returned to the R5, which then frees the buffer.
