* e100: renamed top level for E100/E110 to E1x0Josh Blum2012-07-175-9/+9
| | | | Some minor tweaks to gpmc_to_fifo + timing
* E100: squash E100/E110 top level workJosh Blum2012-07-166-531/+84
| | | | | | Implements timed commands and FIFO control. Uses control and data FIFOs for GPMC. Uses the common core for E100/B100.
* gpmc: tighter timing constraints and easier to route gpmc to fifoJosh Blum2012-07-161-15/+11

| | * e100: offset gpmc to fifo writes by 2 transfersJosh Blum2012-07-151-1/+1
| | | | | | | | | | | | This effectivly works around bus initial transaction issues.

* | e100/b100: bumped compat number for timed commands mergeJosh Blum2012-04-252-2/+2
| | | | | | | | | | There were common FPGA changes and an incompatibility. This should have been done before the merge anyhow.

| | * vita: moved clear register to overlap with nchan registerJosh Blum2012-04-094-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the bug where setting the format clears the vita RX. This is only an issue when the noclear option is set by UHD, because the format register is always so, so it always clears. Note: noclear is there to support the backwards compat API (pre streamer). Now, numchans and clear overlap. This is ok because in the host code, clear and numchans are always used together. All timing meets on N2xx and USRP2.

| | * b100: fix slave fifo data xfer exit conditionJosh Blum2012-04-011-1/+1
| | | | | | | | | | | | | | | | | | | | | When exiting the read/write data state, when the transfer count maxes out/peaks, the fifo read/write signals were getting this condition the cycle after with the state change.

| * b100: slave fifo fix for dst/src ready signalsJosh Blum2012-03-241-1/+1
| | | | | | | | | | | | | | | | Some of the changes my be overkill, but the idea is to be more careful about allowing FIFO IO to occur on transitions. The cal app was able to complete successfully.

* | fifo ctrl: spi core work, fifo ctrl perifs, usrp2 supportJosh Blum2012-03-163-351/+394
| | | | | | | | | | | | | | | | Continued work on simple spi core. Added peripherals input to fifo ctrl so perifs can backpressure fifo ctrl. Copied the implementation into usrp2 core.

* fpga: force -include_global for custom sourcesJosh Blum2012-03-129-13/+16
| | | | | | | | ISE will not recognize custom sources as part of the hierarchy, and thus will not compile (unless its the first macro...). Remove custom sources from the source list, and specially add them with the -include_global option.

|
* usrp2/nseries: added churn to meet timingJosh Blum2012-02-182-2/+4
| | | | | Added churn to readback mux on nseries to make n200r4 meet timing. Also added churn to usrp2 for parallelism, but assigned to zero.
