[OpenBIOS] static and global variable problem

I tried the "info mtree" command and found out that the variable next_grab_slot's address is located in this section:

00000000fff00000-00000000ffffffff (prio 0, R-): ppc_heathrow.bios

next_grab_slots's address is 0xfffda060.

The "R-" seems to indicate that this section is read only explaining why the variable's value can't be changed. I am pretty sure static variables should not be kept in this region. How do we change where static and global variables are stored?
