Where is the Flexi-Hal Board?

[nostifaru]

Hi - might well be missing something entirely obvious here, but I can't find the Flexi-HAL board in the web builder. I can see that it's listed in GitHub (boards/flexi_hal.c), but doesn't seem to pop up anywhere at all in the web builder, I've checked through all the options.

Not sure why that is, but could anyone help?

Thanks!
