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>

Freescale MPC8610HPCD board
===========================


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

    $ make MPC8610HPCD_config
    Configuring for MPC8610HPCD board...

    $ make


Flashing U-Boot
---------------
The flash is 128M starting at 0xF800_0000.

The alternate image is at 0xFBF0_0000
The      boot image is at 0xFFF0_0000.


To Flash U-Boot into the booting bank:

	tftp 1000000 u-boot.bin
	protect off all
	erase fff00000 +$filesize
	cp.b 1000000 fff00000 $filesize


To Flash U-Boot into the alternate bank

	tftp 1000000 u-boot.bin
	erase fbf00000 +$filesize
	cp.b 1000000 fbf00000 $filesize


pixis_reset command
-------------------
A new command, "pixis_reset", is introduced to reset mpc8610hpcd board
using the FPGA sequencer.  When the board restarts, it has the option
of using either the current or alternate flash bank as the boot
image, with or without the watchdog timer enabled, and finally with
or without frequency changes.

Usage is;

	pixis_reset
	pixis_reset altbank
	pixis_reset altbank wd
	pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
	pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>

Examples;

	/* reset to current bank, like "reset" command */
	pixis_reset

	/* reset board but use the to alternate flash bank */
	pixis_reset altbank

	/* reset board, use alternate flash bank with watchdog timer enabled*/
	pixis_reset altbank wd

	/* reset board to alternate bank with frequency changed.
	 * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio
	 */
	pixis-reset altbank cf 40 2.5 10


DIP Switch Settings
-------------------
To manually switch the flash banks using the DIP switch
settings, toggle both SW6:1 and SW6:2.
