OCRAM not accessible on IMX8QM-MEK

We received newer version of the IMX8QM-MEK boards and I was trying to access OCRAM to perform some memory tests. This OCRAM region (0x100000 - 0x13FFFF) doesn't seem to be accessible. I am booting the board using u-boot and loading an application on top of it. I see that this region of memory is not accessible by u-boot as well. 

However this was accessible in the previous version of the board.

I tried using the SC APIs to assign the memory region but wasn't successful (find memory API returns - not found error). What do i need to do to access this region? I presume the SCFW has changed and doesn't allow access?



U-Boot version loaded on the new board - U-Boot 2018.03-imx_v2018.03_4.14.98_2.0.0_ga
