Subject: [PATCH v4 08/33] target/ppc/mmu_common.c: Drop cases for unimplemented MPC8xx MMU
Date: Thu, 09 May 2024 01:36:11 +0200 (CEST) [thread overview]
Message-ID: <71aafa52bdf95e4c82e0ed2f6ca045eaccb56abe.1715209155.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1715209155.git.balaton@eik.bme.hu>
Drop MPC8xx cases from get_physical_address_wtlb() and ppc_jumbo_xlate().
The default case would still catch this and abort the same way and
there is still a warning about it in ppc_tlb_invalidate_all() which is
called in ppc_cpu_reset_hold() so likely we never get here but to make
sure add a case to ppc_xlate() to the same effect.
