Subject: [U-Boot] [PATCH v2 0/3] imx6ull: Fix missing initial output from UART
Date: Wed, 24 Jul 2019 18:09:56 +0300 [thread overview]
Message-ID: <20190724150959.22918-1-igor.opaniuk@gmail.com> (raw)
For Colibri iMX6ULL we have to set pinmux for uart configuration ASAP
(ideally before relocation) to get serial console working. Without this
we miss almost the half of output (U-boot version, CPU defails,
Reset cause, DRAM details etc.).
To achieve this we need to force pinctrl-mx6 to get probed before
relocation and add u-boot,dm-pre-reloc properties to uart pinmux
configuration nodes. Setting pinmux configuration for UART before was done
in board_early_init_f().
