    The Linux coding style guide (Documentation/process/coding-style.rst)
    clearly says:
      It's a **mistake** to use typedef for structures and pointers.
    Besides, using typedef for structures is annoying when you try to make
    headers self-contained.
    Let's say you have the following function declaration in a header:
      void foo(bd_t *bd);
    This is not self-contained since bd_t is not defined.
    To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
      #include <asm/u-boot.h>
      void foo(bd_t *bd);
    Then, the include direcective pulls in more bloat needlessly.
    If you use 'struct bd_info' instead, it is enough to put a forward
    declaration as follows:
      struct bd_info;
      void foo(struct bd_info *bd);
    Right, typedef'ing bd_t is a mistake.
    I used coccinelle to generate this commit.
    The semantic patch that makes this change is as follows:
      typedef bd_t;
      +struct bd_info
