They appear to be available. The dtc/libfdt folder does have the files QEMU
uses.

The fdt32_t type is not there. Here is the full libfdt_env.h file:
#ifndef _LIBFDT_ENV_H
#define _LIBFDT_ENV_H
#include <stddef.h>
#include <stdint.h>
#include <string.h>
#define _B(n) ((unsigned long long)((uint8_t *)&x)[n])
static inline uint32_t fdt32_to_cpu(uint32_t x)
{
return (_B(0) << 24) | (_B(1) << 16) | (_B(2) << 8) | _B(3);
}
#define cpu_to_fdt32(x) fdt32_to_cpu(x)
static inline uint64_t fdt64_to_cpu(uint64_t x)
{
return (_B(0) << 56) | (_B(1) << 48) | (_B(2) << 40) | (_B(3) << 32)
| (_B(4) << 24) | (_B(5) << 16) | (_B(6) << 8) | _B(7);
}
#define cpu_to_fdt64(x) fdt64_to_cpu(x)
#undef _B
#endif /* _LIBFDT_ENV_H */

I’m not sure how to obtain the version of libfdt. I did see a file called
version.lds.
At the top of this file is this text: "LIBFDT_1.2 {"
So maybe I am using version 1.2. Perhaps the configure test should declare a
variable
of the fdt32_t type in the test code.
After doing a git submodule update qemu-system-mips64el compiled successfully.
Thank you.
