From 9caaa3fc460acfe3c6933d40140541d7774e724d Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 10 Aug 2021 06:37:09 +1000 Subject: [PATCH] litesdcard: Use vendor not board type litesdcard provides a macro per vendor (eg xilinx, lattice) and not per board, so modify the fusesoc generator to take a vendor. This will make it easier to add litesdcard to more boards.
