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
