Subject: imx8mp-venice: fix DRAM bus configuration
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=f51559cc583af327c9e4fbe40db3201f2835803c;p=u-boot.git

imx8mp-venice: fix DRAM bus configuration

The DRAM configuration for the 1GB and 4GB imx8mp venice boards had a
bus mapping issue (channel A and B swapped) which creates an invalid
deskewing configuration during training causing the DRAM to not be able
to run at its full bus speed.

Update the various config structures to resolve this.
