165ef20ffa pipistrello: drop rtio fifos for invisible leds
the main board leds are all under the adapter board

also tweak fifo depths a bit in a feeble attempt to circumvent a ISE hang (par
phase 4)

e2cb0e107f pipistrello: really do not request xtrig 2015-06-28 21:11:41 -06:00
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)

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.

fd2def4951 generate MAILBOX_BASE with SoC and use it in runtime
to avoid possible future mismatches between SoC/runtime, constants that can be easily generated from SoC should be defined this way.
