The BCM2835 system uses an AMBA AXI-compatible interface structure. In order to keep the system complexity low and data throughput high, the BCM2835 AXI system does not always return read data in-order 2. The GPU has special logic to cope with data arriving out-of-order; however the ARM core does not contain such logic. Therefore some precautions
