Add support for the Arria 10 SoC development kit to the dac_fmc_ebz
project.
This allows to use the following FMC boards on the Arria 10 SoC development
Kit carrier:
* AD9135-FMC-EBZ
* AD9136-FMC-EBZ
* AD9144-FMC-EBZ
* AD9152-FMC-EBZ
* AD9154-FMC-EBZ
* AD9171-FMC-EBZ
* AD9172-FMC-EBZ
* AD9173-FMC-EBZ
Note that the board in its default configuration is not fully compatible with the
mentioned FMC boards and some slight re-work moving some 0 Ohm resistors is
required. The rework concerns the LA01 and LA05 pins, which by default are
not connected to the FPGA. The changes required are:
LA01_P_CC
R612: R0 -> DNI
R610: DNI -> R0
LA01_N_CC
R613: R0 -> DNI
R611: DNI -> R0
LA05_P
R621: R0 -> DNI
R620: DNI -> R0
LA05_N
R633: R0 -> DNI
R632: DNI -> R0
The main differences between AD9144-FMC-EBZ and AD9172-FMC-EBZ are:
* The DAC txen signals are connected to different pins
* The polarity of the spi_en signal is active low instead of active high
* The maximum lane rate is up to 15.4 Gpbs
To accommodate this all 4 possible txen signals as well as the spi_en
signal are connected to GPIOs. Software can decide how to use them
depending on which FMC board is connected.
Note that each carrier has a maximum supported lane rate. Modes of the
AD9172 (and similar) that exceed the carrier specific limit can not be used
on that carrier. The limits are as following:
* A10SoC: 14.2 Gbps
