From 10a8cc01b32114c6412691206f6402ed3fc50c9f Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 17 Feb 2020 15:17:01 -0300 Subject: [PATCH] imx8qxp_mek: Fix the console command line string Currently the expansion of the console variable leads to the following kernel command line: console=ttyLP0,${baudrate} earlycon root=/dev/mmcblk1p2 rootwait rw , which causes the console to not show characters after the LPUART driver is probed as the 'baudrate' variable is not properly translated. Fix it by splitting the console variable in two parts: one for the ttyLP0 part and the other one for the baudrate, which matches the way it is done on other i.MX targets. Tested by successfully booting a mainline kernel on a i.MX8QXP MEK board.
