Where can I find the linker script used to set up Morello in bare metal mode at EL3?

The _start code in crt0.S located in newlib is used to  initialise Morello for bare metal mode at EL3, but where can I find the linker script for this set up? There are a number of ld files in newlib but it is not clear which, if any are associated with Morello? Where can I find this default linker script please for Morello?
