gf_early_console_putchar() uses __raw_writel() but the standard driver uses writel()/readl(). This means we can't use both on the same machine as the device is either big-endian, little-endian or native-endian. As android implementation defines the endianness of the device is the one of the architecture replace all writel()/readl() by __raw_writel()/__raw_readl() https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/hw/char/goldfish_tty.c#222 Signed-off-by: Laurent Vivier <laurent@vivier.eu> Link: https://lore.kernel.org/r/20201010004749.1201695-1-laurent@vivier.eu 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.
