Add support for Microsemi Polarfire FPGA

[carlosedp]

Add support for Microsemi Polarfire FPGA. This is still a WIP for review.

This PR depends on Libero support added to Edalize on https://github.com/olofk/edalize/pull/212.

[carlosedp]

To test this, I've installed my local Edalize branch supporting Libero, created a workspace, added my branch of blinky project and tried to build but no files were generated. Below the steps:

# Added my blinky local library (with this PR)
fusesoc library add --location ~/repos/fusesoc-blinky blinky-local ~/repos/fusesoc-blinky

# Built for Polarfire FPGA
fusesoc run --target=polarfireeval_es fusesoc:utils:blinky

INFO: Preparing fusesoc:utils:blinky:1.0
INFO: Setting up project
INFO: Set Libero tool option speed to default value -1
INFO: Set Libero tool option dievoltage to default value 1.0
INFO: Set Libero tool option range to default value IND
INFO: Set Libero tool option defiostd to default value LVCMOS 1.8V

fusesoc_utils_blinky_1.0.tcl
INFO: Running

# Got no files
❯ tree

└── fusesoc.conf

I expected the verilog files and the generated script should be created somewhere. Tips?

[olofk]

Well.... I would have expected that too :)

I can't think figure out why there's no build directory created in your workspace. FuseSoc/Edalize should have created something like build/fusesoc_utils_blinky_0/polarfireeval_es-libero where you script will be. I'll try your branch tomorrow and see if I can figure out what goes wrong. It obviously finds and runs your backend so it's super strange

[carlosedp]

Yes, I've added the "echo" command to my backend and it prints the script filename.

I tried it all from scratch but same happens, here's the full output:

❯ mkdir workspace
❯ cd workspace

❯ fusesoc library add blinky-local ~/repos/fusesoc-blinky
INFO: Interpreting sync-uri '/Users/cdepaula/repos/fusesoc-blinky' as location for local provider.

Weird :)

I've reinstalled some things and it's generated!

Now I'm just adjusting some script generation things on both here and edalize. Will push changes soon!

[carlosedp]

Working perfectly with latest commits on edalize. Ready for review.

[olofk]

Many thanks for this and sorry for taking like a million years to review it
