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>

U-Boot for the TQ Systems TQMa6 modules

This file contains information for the port of
U-Boot to the TQ Systems TQMa6 modules.

1. Boot source
--------------

The following boot source is supported:

- SD/eMMC
- SPI NOR

2. Building
------------

To build U-Boot for the TQ Systems TQMa6 modules:

	make tqma6<x>_<baseboard>_<boot>_config
	make

x is a placeholder for the CPU variant
q - means i.MX6Q/D: TQMa6Q (i.MX6Q) and TQMa6D  (i.MX6D)
dl - means i.MX6DL: TQMa6DL  (i.MX6DL)
s - means i.MX6S: TQMa6S  (i.MX6S)

baseboard is a placeholder for the boot device
mmc - means eMMC
spi - mean SPI NOR

This gives the following configurations:

tqma6q_mba6_mmc_config
tqma6q_mba6_spi_config
tqma6dl_mba6_mmc_config
tqma6dl_mba6_spi_config
tqma6s_mba6_mmc_config
tqma6s_mba6_spi_config
