In a private thread, Simon asked about what's needed to get PowerPC migrated to DM_SERIAL. I went and took a look, and to complete the entire DM_SERIAL migration (excluding SPL/TPL) we're actually nearly there. This series first migrates PowerPC (and some NXP Layerscape boards that share history more clearly with PowerPC parts), with the biggest change being to make sure we still use the correct legacy drivers in SPL/TPL (where SPL is extremely constrained). With that out of the way, I looked at what was left. With two exceptions, it's platforms which can be trivially enabled for conversion, and so we do that.
What remains to be converted are: - Xtensa: https://lore.kernel.org/u-boot/20250501230349.GM1261075@bill-the-cat/ - The DS109 platform which has a special reset done over UART: https://lore.kernel.org/u-boot/20250501230530.GN1261075@bill-the-cat/ I believe both of these should be rather clear conversions by someone with the time to do so. -- Tom
