Masahiro Yamada b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
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:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

Board information
-----------------

The evaluation board "pbab01" is thought to be used
together with the SOM.

More information on the board can be found on manufacturer's
website:

http://www.phytec.de/produkt/system-on-modules/phyflex-imx-6/

Building U-Boot
-------------------------------

$ make pfla02_defconfig
$ make

This generates the artifacts SPL and u-boot.img.
The SOM can boot from NAND or from SD-Card, having the SPI-NOR
as second option.
The dip switch "SW3" on the board let choose the boot device.

SW3_1(on), SW3_2(on), SW3_3(off):	Boot first from SD, then try SPI
SW3_1(off), SW3_2(on), SW3_3(off):	Boot from SPI
