Subject: imx: imx8ulp: Remove the TRDC configure from A35
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-logo.png?a=commitdiff_plain;h=aec9b5de44b0c310c1dda82ad0ad7a8bac292db0;p=u-boot.git

imx: imx8ulp: Remove the TRDC configure from A35

As M33 is responsible for TRDC configuration, the settings for A35
nonsecure world access and DMA0 access are moved to M33 image.
So remove the codes to release TRDC and configure it. Just keep
the configurations for reference.
