All SoC devices include a PMC. The PMC is responsible for boot, configuration, partial-reconfiguration, and other platform management tasks, such as security. The PMC includes the deeply embedded ROM code unit (RCU) for device boot and a platform processing unit (PPU) that executes the platform loader and manager (PLM) firmware. The PLM also manages the processing system management (PSM) controller firmware downloads.
Details of the PMC functional units are described in Platform Boot, Control, and Status.
