* Merge branch 'u1e' into merge_u1eMatt Ettus2010-11-1014-18/+623
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * u1e: (130 commits) invert led signals because they are active low duh allow for CS to rise before, at the same time, or after OE better debug pins watch the ethernet chip select on our debug bus fix timing issue on DAC outputs with rev 2. This puts the whole system on a 90 degree phase shift send all gpmc signals to mictor updated pins to match rev2, removed dip switch, etc. seems to compile ok. pins are different on rev2 fixed makefile to compile with our new system add register to tell host about compatibility level and which image we are using move declaration to make loopback compile no need for protocol headers since we're not doing ethernet match the signal names in this design debug pins cleanup properly integrate the new tx chain catch up with tx_policy attach run_tx and run_rx to leds connect atr delay the q channel to make the channels line up on the AD9862 ...

| * Merge branch 'ise12' into u1eMatt Ettus2010-07-191-0/+1
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ise12: move declaration ahead of use put run_tx and run_rx on the displayed LEDs remove warnings add mux and demux to build mux multiple fifo streams into one. Allows priority or round robin split fifo into 2 streams based on first line in each packet precompute udp checksums barely fails timing on gigE/10 and gigE/12, larger fail on udp/10, but all seem to work ok

This is unnerving. experimental mods to make ram loader fully synchronous. Based on IJB's work fixes from IJB from 5/24. Basically connect unconnected wires. removes the icache and pipelines the reads
