+        ---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.

+          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.

           If you say Y here, physical addressing will be extended to
           32-bits through the SH-4A PMB. If this is not set, legacy

+          in process space, and subsequently handing down the entry point
+          to the libc through the ELF auxiliary vector.
+
+          From the kernel side this is used for the signal trampoline.
