From 22a6d11a5472080f38f1ef2def8fffc1a5de091c Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 21 Jun 2020 18:50:22 +0200 Subject: [PATCH] mb/emulation/qemu-q35: Use common early SPI code Tested, it still boots. It is unknown whether this has any effect on emulated hardware, which is most likely not emulating SPI transfers.
