Hello everyone,
I wanted to know what this message that shows u-boot on boot meant:

Clock Configuration:
       CPU0(A53):1600 MHz  CPU1(A53):1600 MHz  CPU2(A53):1600 MHz  
       CPU3(A53):1600 MHz  
       Bus:      400  MHz  DDR:      1600 MT/s  FMAN:     500  MHz
Reset Configuration Word (RCW):
       00000000: 08100010 0a000000 00000000 00000000
       00000010: 14550002 80004012 e0025000 c1002000
       00000020: 00000000 00000000 00000000 00038800
       00000030: 00000000 00001101 00000096 00000001

 The written: CPU0(A53):1600 MHz CPU1(A53):1600 MHz CPU2(A53):1600 MHz CPU3(A53):1600 MHz

indicates that CORE 0, CORE 1, CORE 2 and CORE 3 are running at the 1600MHz frequency?
or tell me what the core frequency is?

I say this because on the board it is possible to disable two cores out of four via software, and when I enable the disabling of the two cores via hardware, u-boot shows me only the writing of CORE 0 (1600MHz ) and CORE 1(1600MHz ).
So I don't understand if this information reported by uboot tells us if the cores are on or off
