Subject: [PATCH 1/3] libfdt: define UINT32_MAX in libfdt_env.h
Date: Thu, 12 Sep 2019 15:01:48 +0900 [thread overview]
Message-ID: <20190912060150.10818-2-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <20190912060150.10818-1-takahiro.akashi@linaro.org>
In the implementation of kexec_file_load-based kdump for arm64,
fdt_appendprop_addrrange() will be used, but fdt_addresses.c
will fail to compile due to missing UINT32_MAX.
So just define it in libfdt_env.h.
