iMX8mm lpddr4 ROM table location Yocto zeus

Hello.

I am looking to enable secureboot in the Yocto zeus branch for iMX8mm.

I am using the following repo link to initialize the repository:

repo init -u https://source.codeaurora.org/external/imx/imx-manifest  -b imx-linux-zeus -m imx-5.4.3-2.0.0.xml

 

In order to use coresight, I need the Embedded Trace Macrocell (ETM) for each core defined in a devicetree, but can not find the address for this board. If I can get the location of the ROM table then I can find the offset for each core (see https://developer.arm.com/documentation/ddi0500/d/debug/rom-table/rom-table-register-summary).

 

This post is requesting the address of said ROM table, or the devicetree file to enable coresight components.

 

Thanks,

-Mitch
