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>

README arm: mvebu: db-88f6820: Add SPL support with DDR init code 2015-07-23 10:39:35 +02:00

Update from original Marvell U-Boot to mainline U-Boot:
-------------------------------------------------------

The resulting image including the SPL binary with the
full DDR setup is "u-boot-spl.kwb".

To update the SPI NOR flash, please use the following
command:

=> sf probe;tftpboot 2000000 db-88f6820-gp/u-boot-spl.kwb;\
sf update 2000000 0 60000

Note that the original Marvell U-Boot seems to have
problems with the "sf update" command. This does not
work reliable. So here this command should be used:

=> sf probe;tftpboot 2000000 db-88f6820-gp/u-boot-spl.kwb;\
sf erase 0 60000;sf write 2000000 0 60000
