michael-west 0971ae69cb Replay buffered TX streamer: Fix gaps in TX
Gaps in transmission were seen when using the replay buffered TX
streamer caused by the Replay block setting the end of burst flag at the
end of every send() call.  This fix adds a flag to the Replay block play
command register to avoid setting the end of burst flag and modifies the
replay buffered TX streamer to use the flag based on the metadata passed
in to the send() call.

michael-west 1c5b744a4d FPGA: Replay block version 1.1
- Add registers to read current record and  play positions.
- Add register to read current space in play command FIFO to allow
  software to avoid overflowing the FIFO.
- Cache base address and size with play command in command FIFO.
- Fix timestamp logic.  Timestamp is only for the first packet of a
  burst.  The increment of 1 for each sample is not accurate because
  it assumed the Replay block was playing at the same rate as the
  Radio, which cannot be assumed.

Maintained backwards compatibility with older API.

Wade Fife 56e53d271e fpga: rfnoc: Make Replay packet length independent of burst size
Before this change, the packet size output by the Replay block during
playback was limited to length of a full memory burst transaction.
This led to relatively small packets during playback (typically
2 KiB) and had other side effects, such as simultaneous playback from
two different memory locations using different packet sizes because of
differences in memory alignment.

With this change, the configured packet size, as set by the register
REG_PLAY_WORDS_PER_PKT, is used for all packets except the last
packet of playback, which can of course be smaller.

Wade Fife df7fd28589 fgpa: rfnoc: Set Replay memory transactions to 2 KiB
This sets the Replay block's counter width so that memory bursts are
up to 2 KiB. Previously, the counter width was fixed, which meant
that wide memories would require especially large buffers and could
exceed the 4 KiB limit imposed by AXI.

Wade Fife 73506997bd rfnoc: Fix noc_shell direction comments
Some comments describing data flow direction were wrong. This commit
updates the Mako files and updates the noc_shell modules with newly
generated versions.
