* Removed 'ifdef for second DCM that was a deign idea for external SRAM on ↵Ian Buckley2010-11-111-49/+4
| | | | | | u2plus. Hardcoded -90 degree clcok from first DCM as final solution

| | | | | | full watermark 2) Put larger FIFO on output of u2plus extramfifo that is compatable with u2_rev3 EMI fixes.
* 1) u2p has added a new signal from the SRAM to the pinout, RAM_ZZIan Buckley2010-11-114-11/+17
| | | | | | | | | | | | | | | which allows the SRAM to be placed in a sleep mode. This pin was erroniously pulled high at the top level rendering the SRAM unusable. 2) Added declaration for extramfifo debug bus which had got deleted at some point in the past 3) Created a debug bundle of signals from extsramfifo to help diagnose problem 1) 4) u2p Rev1 PCB ommits control of any of the SRAM chip selects. Made a code change so that control logic does not rely on the presence of this pin and ensuring that the SRAM is always placed in READ mode in any idle cycles.
* Defaulted all SRAM pins to LVCMOS25 8mA FASTIan Buckley2010-11-111-67/+67

* Placed 2nd DCM into `ifdef DCM_FOR_RAMCLK which is dissabled by defaultIan Buckley2010-11-112-7/+23
