Randy Dunlap 66dbc36121 sh: init: use OF_EARLY_FLATTREE for early init 
commit 6cba655543 upstream.

When CONFIG_OF_EARLY_FLATTREE and CONFIG_SH_DEVICE_TREE are not set,
SH3 build fails with a call to early_init_dt_scan(), so in
arch/sh/kernel/setup.c and arch/sh/kernel/head_32.S, use
CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF_FLATTREE.

Fixes this build error:
../arch/sh/kernel/setup.c: In function 'sh_fdt_init':
../arch/sh/kernel/setup.c:262:26: error: implicit declaration of function 'early_init_dt_scan' [-Werror=implicit-function-declaration]
  262 |         if (!dt_virt || !early_init_dt_scan(dt_virt)) {

Fixes: 03767daa13 ("sh: fix build regression with CONFIG_OF && !CONFIG_OF_FLATTREE")
Fixes: eb6b6930a7 ("sh: fix memory corruption of unflattened device tree")

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.
