Platform/Overdrive: revert streamID DT changes for first SATA port

2019-12-09T17:36:05+00:00

Commit 7a1cd6efbb483564dcf0ff3dda701bd09acf4b08 updated the stream ID assignment for various masters on the Seattle SoC, primarily to address a conflict between the second SATA port and the crypto accelerator on platforms that implement them (B1 silicon). Unfortunately, B0 variants turn out to exist where the stream ID assignment deviates from the observed assignment on the B0 Overdrive that I tested these changes on, leading to DMA access faults when using the first SATA port. Since that port does not share its SMMU with any other masters, let's revert the change to its stream ID assignment in the device tree, and switch back to matching the entire range [0x0, 0x1f].

Platform/Overdrive: fix a typo in the DT

2019-11-28T14:51:15+00:00

DT unit addresses are hex quantities but they should not include the 0x prefix. Note that this is a cosmetic change only. Signed-off-by: Ard Biesheuvel Reviewed-by: Leif Lindholm

Platform/Overdrive: clean up stream ID descriptions in DT

2019-11-28T14:50:17+00:00

Align the DT description of the SMMU topology and stream IDs with the actual routing of the SoC. As with the preceding IORT change, this is mostly a cleanup exercise, but it does actually fix an issue with the CCP crypto accelerator on B1 silicon. Since the CCP shares its SMMU with the second SATA controller, which is only enabled on B1 silicon, we can drop the logic that disables this SMMU on B0 silicon or on platforms that do not expose any SATA ports on the second controller (such as the Cello).

Platform/AMD/OverdriveBoard: build device tree from source

2018-12-11T16:46:07+00:00

Instead of incorporating the prebuilt device tree binary as a FREEFORM FFS file into the build, define a module that contains the source so that the device tree compiler is invoked at build time. The original .dts file is moved into the new module, and cleaned up a little so that explicit phandle properties are dropped, and unused clocks and other redudant pieces are removed as well. The existing prebuilt binary is deleted. Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Ard Biesheuvel Reviewed-by: Leif Lindholm
