Good to get this converted. However, and this addresses some of the questions in the Kconfig patch (which should be part of this patch too), the end result should be supporting: - Full U-Boot is DM only. - SPL works with SPL_DM and (SPL_CI_UDC && SPL_DM). - SPL works with SPL_CI_UDC and !SPL_DM. This does mean adding a new symbol, for SPL, and migrating existing configs to SPL_CI_UDC. It would also be real nice to know if all of the imx6 and imx7 platforms that don't use SPL_DM could use SPL_DM, so we could drop that last case I mentioned above. -- Tom
