It also adds some internal memory segments (OCRAM) to the i.MX7 to allow bare metal application to use them. Last, it adds the SRC device to the i.MX7 processor to allow bare metal application to start the secondary Cortex-A7 core. Note: When running Linux inside Qemu, the secondary core is started by calling PSCI API and Qemu is emulating PSCI without needing access to the SRC device. This is why Linux is using the 2 cores in Qemu even if the SRC is not implemented. This is not the case when running bare metal application (like u-boot itself) that do not rely on the PSCI service being available.
