TSE with SGDMA Busy problem

Things are a little different. We renamed the DMA related components (TSE, SGDMA. memory associated with DMA) within our SOPC system.

Now when start a DMA and read back the DMA status we get an 0x18. That is BUSY + CHAIN_COMPLETED. The 0x85 in the descriptor control byte is still there.

When DMA works , the 0x10 in the DMA status turns into a 0xC (DESCRIPTOR_COMPLETED + CHAIN_COMPLETED. It should be impossible to get a CHAIN_COMPLETED without an accompanying DECRIPTOR_COMPLETED or to get a CHAIN_COMPLETED without clearing the busy or the descriptor control byte but we're managing both.
