ES1000 Memory controller init question

I am working on a system that has a ATI ES1000 (based on radeon)
connected to a MIPS processor and I am trying to figure out how to
initialize the ES1000 SDRAM memory controller.  Where is this
typically done?  I have looked through Xserver driver code, but so far
can't find anything.  Is this typically done with a BIOS extension on
a x86 system or something like that?  Any pointers to code examples or
documentation would be most appreciated as it is next to impossible to
get documentation on this chip.
