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>

How to use U-Boot on PHYTEC phyBOARD-i.MX6UL-Segin
--------------------------------------------------

- Configure and build U-Boot for phyCORE-i.MX6UL:

    $ make mrproper
    $ make phycore_pcl063_defconfig
    $ make

  This will generate SPL and u-boot-dtb.img images.

- The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:

    $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
    $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Jumper settings:

  JP1:   Open: Boot from NAND
       Closed: Boot from SD/MMC1

- Connect the Serial cable to UART0 and the PC for the console.

- Insert the micro SD card in the board and power it up.

- U-Boot messages should come up.
