"earlycon" no need to specify the value string since it uses stdout-path parameters. However when earlycon and normal console are not using the same uart port, we need specify value string to earlycon, this is what we need to do when support dual linux using jailhouse hypervisor. The 2nd linux will use the uart of the 1st linux as earlycon. earlycon=lpuart32,mmio32,0x5a060010,115200 not work for i.MX8QXP. It is because lpuart32_early_console_setup not support little endian. Since the original code is to support UPIO_MEM32BE, so if not UPIO_MEM32, we still take it as UPIO_MEM32BE Acked-by: Fugang Duan <fugang.duan@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> Link: https://lore.kernel.org/r/1576822230-23125-3-git-send-email-peng.fan@nxp.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
