From 7e74b606dd39c46d4378d6f6563f560a00ab8694 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Fri, 27 Mar 2026 19:15:10 +0200 Subject: [PATCH] ARM: OMAP1: Fix DEBUG_LL and earlyprintk on OMAP16XX On OMAP16XX, the UART enable bit shifts are written instead of the actual bits. This breaks the boot when DEBUG_LL and earlyprintk is enabled; the UART gets disabled and some random bits get enabled. Fix that.
