Yes, I got the GateMateA1-EVB board from Olimex, since it is
substantially cheaper than the official CologneChips one, and I have no
use for most of the extra features of the CologneChips board:

I can do some testing on iCE40UP5 (iCEBreaker board) and GateMateA1
(GateMateA1-EVB board). I run Debian on amd64, arm64, and ppc64 (but so
far used yosys on amd64 only).

My use-case is basically that: the experimental f8 CPU
(https://sourceforge.net/p/sdcc/code/HEAD/tree/branches/f8/f8/). I
actually use "simple blinkies" for testing": a basic f8-based SoC, that
runs a program on the CPU that does the blinking. However, I write
System Verilog, so I use sv2v (not yet in Debian) as a preprocessor
before feeding my code into yosys.

P.S.: I saw that yosys 0.40 was just released. I'll do a quick test of
the upstream release in the next few days.
