Yes there was a change to add a 4KB MMU memory area to the link
script, presumably to allow early MMU enable and using that cache
space as SRAM.

I think I will add this feature to the generic .lds file since it does
no harm, and it's a feature I would like to implement one day (early
MMU enable). It might help ARM11 also.
