This is the default order in rk356x-u-boot.dtsi and can be dropped.

sdmmc0 is already enabled in rk3568-bpi-r2pro.dts

Should be a 1:1 copy from kernel.

This Kconfig option does not exits.

Please drop CONFIG_ETH_DESIGNWARE and CONFIG_GMAC_ROCKCHIP.

The following series that add GMAC support for RK3568 and RK3588 will
use DWC_ETH_QOS and DWC_ETH_QOS_ROCKCHIP Kconfig options.

This should not be enabled for rk3568, USB_DWC3_GENERIC provide usb
support.

There should not be any need to enable this driver on rk3568.

Please run moveconfig.py to clean up and re-order the defconfig.
