From c7c637043817eae6f48c33b707b40c9c1b20f199 Mon Sep 17 00:00:00 2001 From: whitequark Date: Thu, 3 Oct 2019 05:54:12 +0000 Subject: [PATCH] Reorganize resource taxonomy. The current hierarchy isn't particularly well suited to resources like SDRAM or NOR flash, so make it much less fine-grained but easier to use and less nitpicky. --- nmigen_boards/arty_a7.py | 2 +-
