x86: Update mpspec to build on 64-bit machines
At present this uses u32 to store an address. We should use unsigned long and avoid special types in function return values and parameters unless necessary. This makes the code more portable. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
