Paul Mackerras	18120f153d	MMU: Implement a vestigial partition table ... This implements a 1-entry partition table, so that instead of getting the process table base address from the PRTBL SPR, the MMU now reads the doubleword pointed to by the PTCR register plus 8 to get the process table base address. The partition table entry is cached. Having the PTCR and the vestigial partition table reduces the amount of software change required in Linux for Microwatt support.
