This is somewhat unfortunate, as I have been working on the same thing and have demonstrated the STM32F429 Discovery Kit at ARM TechSymposium Europe in December and submitted a talk for LinuxCon Japan. https://github.com/afaerber/afboot-stm32 https://github.com/afaerber/linux/commits/stm32 On a brief look, it seems you are further along in terms of code quality and documenting. Do you spot anything that's missing in your series and could be added from my branch? The clk controller maybe? Also I already started looking into gpio and usb drivers. Me too, I skipped DMA support though.
