SSPM is "Secure System Power Manager" that provides power control in
secure domain. The initialization flow is to load SSPM firmware to
its SRAM space and then enable.
It takes 21 ms to load sspm.bin.

CBFS: Found 'sspm.bin' @0x21680 size 0xa815 in mcache @0xffffeac4
mtk_init_mcu: Loaded (and reset) sspm.bin in 21 msecs (137348 bytes)
TEST=we can see the sspm logs.
