Istvan Csomortani 8e25bc01b3 all: Change tab to double space 
Occasional file parsing and restructuring become a pain, if tabs exists
in code. General rule of the repos is tab always a double space.

Lars-Peter Clausen 287770a201 axi_dmac: Fix tlast generation on AXI stream master 
For the AXI stream interface we want to generate TLAST only at the end of
the transfer, rather than at the end of each burst.

Lars-Peter Clausen 8a2b29cdbe axi_damc: Add xfer_req to the FIFO source interface 
The xfer_req signal will be high if DMA core the is expecting data.

Lars-Peter Clausen 36ef882da0 axi_dmac: data_mover: Improve timing 
We do not know which 'last' condition to use before hand, but we can pre-compute
the result for both conditions and then use them. This removes the comparison
from the already pretty long combinatorial path.

Also simplify a few expressions.

Lars-Peter Clausen df1c4f0786 axi_dmac: data_mover: Improve timing 
The pending_burst signal and the expression id != request_id are almost
identical. pending_burst goes high with a delay of one clock cycle, but the
important thing is that it goes low on the same clock cycle as the expression.
By using pending_burst here instead of 'id != request_id' we can reduce the
fanout of the 'id' register and improve the timing of the core.

Lars-Peter Clausen f02ba999ae axi_dmac: Add support for DMA bus widths other than 64 bit 
There were a few place in the core where it assumed a 64-bit wide bus. Make this
configurable using parameters. The patch also adds support for having different
DMA bus widths on the source and destination side.

Lars-Peter Clausen 6da9c65a08 axi_dmac: Add support for zero latency transfer switching 
Right now there is always a period of one clock cycle where we can not transfer
any data when switching between two transfers. This patch modifies the data
mover to allow for zero latency. This fixes problems on the FMCOMMS1 platform
