26e8ebcd7c watchdog: mpc8xxx: Make it generic
mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

6a8c36b936 board: cssi: Add MIAE & VGoIP devices
This adds support for the MIAE and VGoIP devices.
Those devices have the same CPU board that the MCR3000_2G board.

The devices are very modular, they are provided with
interchangeable front and back panels.

Linux kernel is shipped with a device tree which contains all
possible setups, and U-boot eliminates unrelated nodes based on
detected hardware.

This patch was originally written by Charles Frey who's
email address is not valid anymore as he left the company.

dac3c6f625 board: cssi: Add new board MCR3000_2G
This adds a new board from CS GROUP. The board is called
MCR3000_2G, and has a CPU board called CMPC885.

That CPU board is shared with another equipment that will
be added in a later patch.

That board stores Ethernet MAC addresses in an EEPROM which
is accessed using SPI bus.

7df55bb9b5 board: MCR3000: Modernise the settings to properly work on lastest u-boot version
Both U-boot and Linux kernel have grown over the last releases
and don't fit anymore in the 2M EPROM of the board.

So, rework the setup to allow storing the Linux kernel image
on the UBIFS NAND Flash.

Also add support to FIT images as this is what the Linux kernel
look like nowadays.

Also increase CFG_SYS_BOOTMAPSZ to 32Mbytes and define
CONFIG_SYS_BOOTM_LEN with the same value, otherwise it defaults
to 8M which is not sufficient anymore with nowadays Linux kernels.

And set the netmask to 255.255.255.0 as a class C address is used.

99e2fbcb69 linker_lists: Rename sections to remove . prefix
Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

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>

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.
