From the LinuxSH CVS (I can write new ones if these are inadequate):
SuperH SCI (serial) support
CONFIG_SH_SCI
Selecting this option will allow the Linux kernel to transfer
data over SCI (Serial Communication Interface) and/or SCIF
which are built into the Hitachi SuperH processor.
If in doubt, press "y".
Use LinuxSH standard BIOS
CONFIG_SH_STANDARD_BIOS
Say Y here if your target has the gdb-sh-stub package from
www.m17n.org (or any conforming standard LinuxSH BIOS) in FLASH
or EPROM. The kernel will use standard BIOS calls during boot
for various housekeeping tasks. Note this does not work with
WindowsCE machines. If unsure, say N.
GDB Stub kernel debug
CONFIG_DEBUG_KERNEL_WITH_GDB_STUB
If you say Y here, it will be possible to remotely debug the SuperH
kernel using gdb, if you have the gdb-sh-stub package from
www.m17n.org (or any conforming standard LinuxSH BIOS) in FLASH or
EPROM. This enlarges your kernel image disk size by several megabytes
but allows you to load, run and debug the kernel image remotely using
gdb. This is only useful for kernel hackers. If unsure, say N.
