You are right psim takes a lot of arguments. :)  I long ago gave up
invoking it by hand.  Look at c/src/lib/libbsp/powerpc/psim/tools.
There is a script called psim which can be linked to psim-gdb. 
Depending
on how it is invoked, it sets up run or gdb for psim.

It is not executable in the source tree and has to have the first line
modified to indicate the shell.
