+ ---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. Other platforms, such as the Solution Engine
+ boards typically map RAM at 0C000000.
+
+ Tweak this only when porting to a new machine which does not
+ already have a defconfig. Changing it from the known correct
+ value on any of the known systems will only lead to disaster.

+config MEMORY_SIZE

+ default "0x00400000"
+ help
+ 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.
