AM3358: Beaglebone Black AM3358 processor replacement software related questions

Hi,

We have a hardware design based on Beaglebone Black (AM3358 1000MHz) and the software was developed and built using Yocto build system:
poky: rocko branch tag "rocko-18.0.3"
meta-ti: rocko branch tag "ti2018.03"
MACHINE = am335x-evm

Now the AM3358 microcontroller 1000MHz is not available for many months. So we are thinking to use AM3352 microcontroller 600MHz as a replacement. The questions arise:
1. Can the software we developed for AM3358 (including u-boot, device tree, Linux kernel, root fs, ...etc.) run on AM3352 without any modification?
2. If the software needs to be modified, what needs to be done at different levels (u-boot, device tree, Linux kernel, ...etc.)?

Here is the replacement we are looking into (taken from the AM335x data sheet):

Thank you for your help!
