Linker script files (.ld) are unique to the development environment: 
compiler, libraries, etc.  They are not peculiar to the processor 
flavor, therefore you can take a LPC21xx, LPC22xx, LPC23xx, or whatever, 
make a few changes to the top of the file where the MEMORY SIZEs are, 
and use them.

The scripts essentially describe where to put what.  And before I get 
flamed, yes, there are slightly different arrangements of memory between 
the LPC products where an external memory bus is available..

The files are not hard to read, if you are on Linux: 'info ld' and look 
at the "scripts" menu entry.  If you are Cygwin, well..., YMMV.  
Embedded programming is an acquired skill / art-form, not a turnkey 
operation.

Reminds me of "... teach a man how to fish ...".
