Things done this week: * Improvements in arm machdep code, especially in pmap_devmap mapping code, allowing first-level nodes in DTS files to be mapped. * Trying to refactor mv port, but this will be not so easy, as mv window decode mechanism needs access to many different SoC registers at initarm() stage. I need to rethink some ideas of dynamic pmap_devmap mapping to handle this scenario properly. Plans for next week: * Think about passing trapframes in interrupt handlers in a way better than multiplexing it with user supplied argument in arm_intr_data structure. * Fix OMAP L2 cache controller issue Regards, Jakub Klama
