[PATCH v1 0/2] Drop ignore_memory_transaction_failures for xilink_zynq

[PATCH v1 0/2] Drop ignore_memory_transaction_failures for xilink_zynq

[Chao Liu]

The ignore_memory_transaction_failures is used for compatibility
with legacy board models. 

I attempted to remove this property from the
xilink_zynq board and replace it with unimplemented devices to 
handle devices that are not implemented on the board.

  xilink_zynq: Add various missing unimplemented devices
  xilink-zynq-devcfg: Fix up for memory address range size not set
    correctly

[PATCH v1 1/2] xilink_zynq: Add various missing unimplemented devices

[Chao Liu]

Add PMU, CAN, GPIO, I2C, and other as unimplemented devices.

Remove a ignore_memory_transaction_failures concurrently.

This allows operating systems such as Linux to run emulations such as xilinx_zynq-7000
