Output section type
...................

   Each output section may have a type.  The type is a keyword in
parentheses.  The following types are defined:

`NOLOAD'
     The section should be marked as not loadable, so that it will not
     be loaded into memory when the program is run.

`DSECT'
`COPY'
`INFO'
`OVERLAY'
     These type names are supported for backward compatibility, and are
     rarely used.  They all have the same effect: the section should be
     marked as not allocatable, so that no memory is allocated for the
     section when the program is run.

   The linker normally sets the attributes of an output section based on
the input sections which map into it.  You can override this by using
the section type.  For example, in the script sample below, the `ROM'
section is addressed at memory location `0' and does not need to be
loaded when the program is run.  The contents of the `ROM' section will
appear in the linker output file as usual.
     SECTIONS {
       ROM 0 (NOLOAD) : { ... }
       ...
     }
