From 13ec6a03ab8a517fa80c7e99e4f08a249648acce Mon Sep 17 00:00:00 2001 From: Rob Barnes Date: Tue, 14 Jul 2020 13:23:43 -0600 Subject: mb/google/zork: Change SPI fast speed to 66mhz Morphius cannot support 100Mhz fast SPI causing it to not boot. Downgrade all zork boards to fast=66mhz and normal=33mhz to be safe.
