Subject: [PATCH edk2-platforms v2 4/8] Silicon/AMD/Styx: clean up stream ID mappings for SMMU
Date: Wed, 27 Nov 2019 19:44:35 +0100	[thread overview]
Message-ID: <20191127184439.16793-5-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20191127184439.16793-1-ard.biesheuvel@linaro.org>

Tighten the stream ID mappings for the SMMU to only cover the stream IDs
that are actually being issued by the respective masters. This is
mostly just a cleanup exercise, since specifying unused stream IDs does
not typically create any problems. However, the CCP crypto accelerator
on B1 silicon actually uses stream IDs that we assigned to the second
SATA controller, so there this actually fixes a problem.

Since the crypto accelerator shares its SMMU with the second AHCI
controller, we can drop the logic that hides the associated IORT
node when running on B0 silicon.
