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>

4c4ca6cdd5 board: MCR3000: use new DM watchdog
This patch switches MCR3000 board to the new DM watchdog.

The change in u-boot.lds is because MCR3000.o grows a bit
with this patch and doesn't fit anymore below env_offset on
some versions of GCC.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

0fb6220565 board: MCR3000: Use smaller flash sector for environment
Latest versions of u-boot have increased in size and require more
than the 256kb allocated to it.

The MCR3000 board is equipped with an AM29LV160DB boot flash which
is organised as follows:
- One 16kb block
- Two 8kb block
- One 32kb block
- Thirty one 64kb blocks

At the time being, u-boot is a single piece occupying the 256 first
kbytes, then the environment is stored in the following 64kb block

The environment being quite tiny, we save one 64kb block by embedding
the environment in the first 8kb block, hence allowing to increase
the monitor size to 320kb.

b3ede33170 board: MCR3000: cleanup config
Some config is redundant with Kconfig. Fix it.
Also remove unused configs
Move SDRAM_MAX_SIZE in the only place it is used

include/environment.h already defines CONFIG_ENV_SIZE
from CONFIG_ENV_SECT_SIZE and defines CONFIG_ENV_ADDR as
(CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET)

remove BOOTARGS as bootargs is set by the different boot commands

Fix CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE to be in
line with CPM DPRAM organisation

Remove CONFIG_SYS_GBL_DATA_SIZE, CONFIG_SYS_GBL_DATA_OFFSET and
CONFIG_SYS_INIT_SP_OFFSET which are unused
