help
"Bare CPU" aka "unknown" means an SH-based system which is not one
of the specific ones mentioned above, which means you need to enter
all sorts of stuff like CONFIG_MEMORY_START because the config
system doesn't already know what it is. You get a machine vector
without any platform-specific code in it, so things like the RTC may
not work.
This option is for the early stages of porting to a new machine.

---help---
Computers built with Hitachi SuperH processors always
map the ROM starting at address zero. But the processor
does not specify the range that RAM takes.
The physical memory (RAM) start address will be automatically
set to 08000000, unless you selected one of the following
processor types: SolutionEngine, Overdrive, HP620, HP680, HP690,
in which case the start address will be set to 0c000000.
Tweak this only when porting to a new machine which is not already
known by the config system. Changing it from the known correct
value on any of the known systems will only lead to disaster.

This sets the default memory size assumed by your SH kernel. It can
be overridden as normal by the 'mem=' argument on the kernel command
line. If unsure, consult your board specifications or just leave it
as 0x00400000 which was the default value before this became
configurable.
