- fw/common/Makefile: generate related definitions from io.h (from IBDG)
- fw/Makefile: build the various firmware elements (from IDBG, without the
target parts)
- fw/boot/Makefile, fw/atspi/Makefile: add ../common to include path
- fw/boot/config.h, fw/atspi/io.h: moved to ../common
- fw/common/config.h: updated comment - it's no longer specific to boot.c
