Changes since v2:
* Update subject-line for the patch.
* Fix commit message.
* Add proper comments for changes.
Changes since v1:
* Added
This patch adds earlyprintk support for i.MX8MQ SoC based
boards.
As with most of other debug code for other platforms, uart is
initialized by bootloaders(for instance u-boot[1]).
