Tree structure: - sys/arch/sh3: sh3 generic code As commented, in-chip device drivers are put into sys/arch/sh3/dev. - sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW) - sys/arch/mmeye: Brains mmEye, www.brains.co.jp MI source code includes couple of #ifdef for sh3-coff support. (sh3 uses coff or elf) Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3, to compile the tree (due to last minute tree structure change).
