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.

Paul Mackerras	ec5730a75a	tests: Add tests for lq/stq and lqarx/stqcx. ... Lq and stq are tested in both BE and LE modes (though only 64-bit mode) by the 'modes' test. Lqarx and stqcx. are tested by the 'reservation' test in LE mode mode (64-bit). Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	4 years ago
Paul Mackerras	e7a08f33eb	tests: Add a test for the load-reserve and store-conditional instructions ... This checks that the instructions seem to update memory as expected, and also that they generate alignment interrupts when necessary. We don't check whether the memory update is atomic as we don't have SMP yet. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	4 years ago
