Robert Jördens 55708e8678 pipistrello: drop bitgen_opt change (done upstream) 2015-07-29 11:45:15 -06:00
Robert Jördens 67715f0d2e pipistrello: only put serdes on the lower ttls
this setup is getting a bit power hungry.

pmt0, 1 (rtio channels 0, 1): 4x in and out
ttl0, 1 (rtio channels 2, 3): 4x out
ttl2 (rtio channel 4): 8x out

Robert Jördens 9dfbf07743 pipistrello: use 4x serdes for rtio ttl
pipistrello: do not wait for lock on startup

LCK_cycle:6 was added in 6a412f796e1 (mibuild). It waits for _all_
DCM and PLLs to lock (probably irrespective of STARTUP_WAIT).

Robert Jördens 23eee94458 pipistrello: add notes to nist_qc1 about dds_clock
* remove xtrig from the target as it is not usually connected (used for
  dds_clock) and ignore PMT2/BTN2 as C:15 is used for dds_clock.
* this also aligns the ttl channel numbers with kc705/nist_qc1 (two pmt
  inputs followed by 16 ttl outputs followed by leds)

Sebastien Bourdeauducq 938e1c2842 Remove UP support.
The only advantage of UP is to support the Papilio Pro, but that port is also very limited in other ways and the Pipistrello provides a more reasonable platform that also supports AMP.

On the other hand, RPCs on UP are difficult to implement with the session.c protocol system (without an operating system or coroutines), along with many other minor difficulties and maintainance issues. Planned features such as watchdogs in the core device are also difficult on UP.
