Istvan Csomortani 4684dc03ce dac_fmc_ebz/a10soc: Use balanced optimization mode 
Always a good idea to start from default, and change optimization mode
of the tool if it's strict necessary.

Lars-Peter Clausen 6d31a437aa dac_fmc_ebz: Add initial Arria10 SoC support 
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
