From eecd37e105f0137af0d1b726bf61ff35d1d7d2eb Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 3 Dec 2019 12:58:52 -0800 Subject: drivers: Fix boot problem on SuperH SuperH images crash too eearly to display any console output. Bisect points to commit 507fd01d5333 ("drivers: move the early platform device support to arch/sh"). An analysis of that patch suggests that early_platform_cleanup() is now called at the wrong time. Restoring its call point fixes the problem.
