![]() While many systems will place raw data here, others certainly do place SW partition tables, and perhaps even filesystems, in the HW partitions. SW can place whatever data structures it wants into these HW partitions the interpretation of any data stored here is up to the SW or HW that reads and interprets it, e.g. The U-Boot environment is located at the end of the primary eMMC hardware boot area partition just before the config block (see below). U-Boot is now booted off the primary eMMC hardware boot area partition (e.g. > The boot HW partitions are block storage just like any other.
