Subject: [RFC PATCH 02/16] hw/arm/smmuv3: Update translation config to hold stage-2
Date: Sun,  5 Feb 2023 09:43:57 +0000	[thread overview]
Message-ID: <20230205094411.793816-3-smostafa@google.com> (raw)
In-Reply-To: <20230205094411.793816-1-smostafa@google.com>

In preparation for adding stage-2 support. Add it's configuration.

They are added as SMMUS2Cfg in SMMUTransCfg, SMMUS2Cfg hold configs
parsed from STE:
 -tsz: Input range
 -sl0: start level of translation
 -affd: AF fault disable
 -granule_sz: Granule page shift
 -vmid: VMID
 -vttb: PA of translation table

They will be used in the next patches in stage-2 address translation.

No functional change intended.
