Harald Welte 1d271dea3f Calypso TPU: Introduce TPU debug mode 
Using #define TPU_DEBUG, we can now send the full TPU RAM contents
to the host PC (using a sercomm DLCI) at the time of tpu_enable()
which is very helpful for TPU debugging.

Harald Welte 3f3a84d516 Calypso TPU: initialize TPU RAM to zero at tpu_init() time 2010-02-23 01:44:37 +01:00
Harald Welte c7224b79bd Calyspo TPU: make add_mod5000() accept signed values 
Sometimes we want to 'add' a negative value but still want the
result to be correct!

Harald Welte bb263dcc70 TRF6151: close the Rx (Downlink) window after ABB is closed 
There is no point in keeping the receiver running after we have
told the ABB to no longer receive anything.

Harald Welte 2dff711bc7 TWL3025: Ensure we don't perform downlink calibration too early 
If we perform the downlink calibration too early, the TRF6151 might
not yet provide a stable signal and we'll not be able to receive
anything.

From the desired "BDLENA" time, we subtract all the delays and
latencies to determine the point in time at which the calibration
process should start.

Harald Welte e943638a92 sercomm_cons: Utilize msgb's better, don't always end at \n 
In the sercomm_cons layer, ee used to enqueue a msgb for sending
every time there is an end-of-line.  However, if we send a number
of very short lines, we easily run out of msgbs.

Now we check how much msgb backlog there is in the transmit queue,
and decide to skip the end-of-line flushing if needed.

This still doesn't solve all our problems, but its still a useful
mechanism.

The only remaining part is the 'debug' part

Harald Welte 2df0b01363 frequency error is actually twice of what we thought. 
The cause is really not clear.  The formual using 2*Pi to convert
from radians to frequency is perfectly correct.

However, measurements with various test equipment (including Racal 6103)
have shown our frequency error estimate is always off by a power of two...
