Subject: [PATCH v2 0/3] libfdt: prepare for (U)INT32_MAX addition
Date: Fri,  1 Nov 2019 17:11:45 +0900	[thread overview]
Message-ID: <20191101081148.23274-1-yamada.masahiro@socionext.com> (raw)

As you may know, libfdt in the upstream DTC project
added referenced to (U)INT32_MAX.

The kernel code has three files to adjust:

include/linux/libfdt_env.h
arch/powerpc/boot/libfdt_env.h
arch/arm/boot/compressed/libfdt_env.h

Instead of fixing arch/arm/boot/compressed/libfdt_env.h,
it is pretty easy to refactor the ARM decompressor
to reuse <linux/lbifdt_env.h>
So, 2/3 simplifies the Makefile and deletes its own
libfdt_env.h

On the other hand, the PPC boot-wrapper is a can of worms.
I give up refactoring it.
Let's keep it closed, and just update arch/powerpc/boot/libfdt_env.h

Changes in v2:
 - Fix ppc libfdt_env.h

Masahiro Yamada (3):
  libfdt: add SPDX-License-Identifier to libfdt wrappers
  ARM: decompressor: simplify libfdt builds
  libfdt: define INT32_MAX and UINT32_MAX in libfdt_env.h
