From: Thierry Escande <thierry.esca...@linaro.org> The ADSP fastrpc provides 3 context banks and are assigned to IOMMU context banks 23, 24 and 25; using SIDs 0x804, 0x805 and 0x806. The CDSP fastrpc provides 5 context banks and are assigned to IOMMU context banks 5, 6, 7, 8 and 9; using SIDs 0x1001 through 0x1005. Add these to their respective remoteproc.
The lower 4 bits of the SID is used to identify the context bank when
communicating with the fastrpc firmware, so this gives the reg values.
