The unmodified U-boot from the last two releases can not run on any SH board, you can consider that SH arch is unmaintained. > Signed-off-by: Paul Burton <paul.burton@imgtec.com> > Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> > --- -- Best wishes, Vladimir

Convert the sh architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for sh this is primarily a matter of moving code. Feedback from architecture maintainers is welcome.
