i.MX8/8X/8M are 3 soc families. i.MX8/8X share similar architecture, so code mostly under imx8 or arch-imx8 i.MX8MQ/MM share similar architecture, so code mostly under imx8m or arch-imx8m. > > The problem here is that files from those directories are referenced in > multiple places and the "imx8m"/"mx8m" is all over in the header files and > sources so once we decided on either naming one tree would have to make a > lot of changes either adding or removing that 'i' before "mx8m". For newer i.MX SoCs, we will add the "i" to represent i.MX brand. > > Can anybody responsible tell _WHICH_ one is going to make it into the main > source tree?
