The DTC v1.5.1 added references to (U)INT32_MAX. This is no problem for user-space programs since <stdint.h> defines (U)INT32_MAX along with (u)int32_t. For the kernel space, libfdt_env.h needs to be adjusted before we pull in the changes. In the kernel, we usually use s/u32 instead of (u)int32_t for the fixed-width types. Accordingly, we already have S/U32_MAX for their max values. So, we should not add (U)INT32_MAX to <linux/limits.h> any more. Instead, add them to the in-kernel libfdt_env.h to compile the latest libfdt. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Rob Herring <robh@kernel.org>
