3. add new structures for SoC access
4. Convert arch, driver and boards file to new SoC
5. remove legacy code, if all boards and drives are ready
+
+2013-10-30 Andreas Bießmann <andreas.devel@googlemail.com>:
+
+The goal is almost reached, we could remove the CONFIG_AT91_LEGACY switch but
+remain the CONFIG_ATMEL_LEGACY switch until the GPIO disaster is fixed. The
+AT91 spi driver has also some CONFIG_ATMEL_LEGACY stuff left, so another point
+to fix until this README can be removed.
