Subject: imx: imx8mm/imx8mn_beacon: Remove redundant code
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=448616126b6c9417f566d6a11040fde2971f2b90;p=u-boot.git

imx: imx8mm/imx8mn_beacon: Remove redundant code

The Ethernet controller and PHY use the device tree info to
configure themselves, so it's not necessary to manually do it
in the board file.  This permits the removal of a bunch of headers
as well.
