I.MX8DXP board bring up

Hi,

Based on BSP L4.14.98_2.3.3, I have some questions about porting i.MX8DXP SOC.

scfw (v1.3.3) porting kit: no die target in makefile for DXP, only qm/qx/dxl supported. how to build to suit DXP SOC, or just use "qx" for DXP as same as QXP?
linux/u-boot: no machine or configuration for DXP, do I need porting this by myself(reference from imx8qxpc0mek)? or any better suggestion?
MCUXpresso SDK(for CM4): if the part number of DXP is MiMX8DX6AVLFZAC, almost pin-to-pin compatible as MiMX8QX6AVLFZAC(imx8qxpc0mek used), do I need MUST to change this SDK necessarily?

Thanks,

1\ You need to use the qx

2\No, you do not need. There are different machine name imx8qxpc0mek imx8dxmek, and uboot configue they are uboot_config_imx8dxmek uboot_config_imx8qxpc0mek

3\ No, But they use different device tree, On i.MX 8QuadMax and 8QuadXPlus, multiple partitions are supported.
Due to the board design, flash.bin and the DTB need to be matched. If
flash.bin includes the Cortex-M4 partition, use x-rpmsg.dtb.
