[U-Boot] show_boot_progress

[Abdullah YILDIZ]

I use u-boot version 1.3.3. The function call __show_boot_progress is
defined in common/main.c as

void inline __show_boot_progress (int val) {}

There are many calls to this function in particular locations with
specific parameters. But it does nothing. What is the purpose of this?

Since I'm not a very good programmer, I also wonder the meaning of
void inline show_boot_progress (int val) __attribute__((weak,
alias("__show_boot_progress")));

Is it a directive to the compiler?
