Can you explain a bit more? If you'd like to change the CPU register
values manually, it can be done via gdb.
Other hardware registers can be altered in gdb too if the
corresponding page is mapped.

Or do you mean, you have a board where some device can modify CPU
registers directly and you'd like to emulate this board?

P.S. qemu-devel@ has sometimes really lots of messages daily. It makes
sense to add a maintainer of related subsystem to CC, so your question
doesn't get lost.  The official Leon3 and Grlib maintainer is Fabien
Chouteau <chouteau@adacore.com>.
The whole list of maintainers is available in the MAINTAINERS file.
