Groundwork for supporting boards beyond the Red Pitaya (we're adding the Fast-Servo). Introduces a per-board "target" layer so others can be added cleanly. This PR only abstracted the Red Pitaya board. We are already using this patch in https://git.m-labs.hk/M-Labs/nix-servo.
Changes as follows:
gateware/targets/with aPitayaSoCthat holds all the Red Pitaya hardware that used to live inLinienModuleLinienModulenow gets the soc passed in and goes through it for hardware, so it isn't tied to the Red Pitaya anymoreRootModule,PitayaSoCreplaces itcsrmap.pyThis shouldn't change anything for the Red Pitaya. The generated csrmap has the same register names and addresses as before (just a few lines reordered), and the gateware tests still pass.
Still to come as separate PRs: the actual Fast-Servo target + its gateware, a
--platformoption to pick the board, and the hardware-specific parameters.Based on Jakub Matyas (@elhep) work: elhep@b73eea0
