The final version of IPQ6000 (SoC id: IPQ6000, SBL version:
BOOT.XF.0.3-00086-IPQ60xxLZB-1) has a max design frequency
of 1.2GHz, so add this CPU frequency.

I can't find anything to support that.

Maybe Sricharan can help out here.

Based on the instructions in the link above, is there anything else I need to do?

Thanks,

I think Kathiravan only wanted to make sure you have the latest bootloader.

Looking at the documentation, I don't see a 1.2 GHz frequency level for
this platform.

But from the merchant's publicity, ipq6000 is 1.2GHz:

Could you try to boot the BSP software and read out the related
registers to determine the real CPU frequency?

Or perhaps, if there's a cpufreq driver (I don't know), check syfs

1. The CPU frequency on OEM firmware is 1.2GHz.
2. The CPU frequency on the BSP kernel is 1.2GHz.
