   Target.ld is a file that tells ld how to link the application, it
says where are the different sections linked. It is
called a linker script. You can read further on linker scripts in the
documentation of the GNUPro Toolkit (for example),
concretely read the chapter for linker scripts in the document "GNUPro
Toolkit, GNUPro Development Tools":
www.redhat.com/docs/manuals/gnupro

eCos prepares its own linker script depending on the booting scheme that
you have selected with the CYG_HAL_STARTUP
option.
