Specify memory region using Linker script


Hi:

I am very new to embedded systems and have a basic question regarding linker
scripts. How do I, in my linker script specify a memory region that is
initially empty. No input sections. I want a certain memory region allocated
for a certaon size.
 I thereafter intend to specify in my code, that certain objects when created
are allocated memory from this region by using the __attribute((section= ..
command.

As i understand if there are no input sections, the linker does not create the
memory region.

Any insights will be highly appreciated.

Thanks in advance.

-R.
