Dhiru Kholia 781d83bab6 Add support for EBAZ4205 'Development' Board 
Usage:

```
./ebaz4205.py --cpu-type=vexriscv --build --load
```

```
$ pwd
litex-boards/litex_boards/targets
```

Tip: Use `GTKTerm` to connect to /dev/ttyUSB0 (usually) and interact
with the LiteX BIOS.

- The existing 'Zybo Z7' example

Note: The `PS7` stuff remains untested via LiteX for now.

We can still try to reduce it, but enabling Master should not use that much LCs.

Florent Kermarrec 0f648ac4ef 1bitsquared_icebreaker: Add test code to use LiteSPI. 
Both XiP from SPI(1X) or QSPI(4X) are working, but resource usage is currently
too high to be able to switch to it by default. We'll first try to reduce it.
