SDMA configuration register needs to be set up only once and doesn't
belong to drivers. Also, the value to be used is different on mpc885.
So do the init in cpu_init_f() with 0x40 for mpc885 and 0x1 for others.

It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0". However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".

In order to use QMC mode in the CPM, a SCC requires more space
in parameter RAM.
After SCC1 there is I2C parameter RAM and after SCC2 there is
SPI parameter RAM. MPC866 and MPC885 can already relocate I2C and.
SPI parameter RAM.
But in order to free space after SCC3 and SCC4, SMC1 and SMC2
need to be relocated. In order to do so, a CPM microcode patch
is required.
Binary data for that patch is copied from Linux kernel.

MPC885 CPU has the following ERRATA:
When the USB controller is configured in Host mode, and the
SOF generation (SFTE=1 in USMOD register) is being used,
there may be false CRC error indication in other SCCs.
Although the data is received correctly, the CRC result
will be corrupted.
Add capability to load the related microcode to fix it.
The microcode binary data is copied from Linux kernel.
Other microcode will be added in following patch so make it
a Kconfig choice.

Using SMC relocation microcode patch or USB-SOF microcode patch
will disable DPRAM memory from 0x2000 to 0x2400 and from 0x2f00
to 0x3000.
At the time being, init RAM is setup to use 0x2800-0x2e00, but
the stack pointer goes beyond 0x2800 and even beyond 0x2400.
For the time being we are not going to use any microcode patch
that uses memory about 0x3000, so reorganise setup to use:
- 0x2800 - 0x2e00 for init malloc and global data and CPM buffers
- 0x3000 - 0x3c00 for init stack

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.

This adds a new board from CS GROUP. The board is called

That CPU board is shared with another equipment that will

Copied from e83a7e94532 ("powerpc/mpc83xx: Zero boot_flags arg for
calling board_init_f()")
The argument boot_flags of board_init_f() is not used at all in the
powerpc specific board.c init sequence. Now with the generic init
sequence, this boot_flags arg is used by board_init_f().
This patch sets the r3 register that is used to pass the boot_flags

call to avoid unknown content to end up in gd->flags.

As explained by Wolfgang, historically PowerPC would do a number of
things to hand-optimize placement of the binary on NOR flash in order to
maximize utilization of very scarce resources. These days, we simply
aren't optimizing our binary layout for NOR flash placement and it's
quite likely this wasn't working as intended. Furthermore, this level
of optimization makes it difficult to have version_string be a global,
instead of a weak and overridden value, and so make more progress on
reproducible builds, which is a current concern.
Move to having PowerPC no longer store version_string in the early part
of text so that it might be part of the first page of NOR and instead
use the same declaration everyone else does.

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

We should not use typedefs in U-Boot. They cannot be used as forward

Drop the typedef and rename the struct to remove the _s suffix which is

Commit f3729ba6e7b2 ("watchdog: mpc8xx_wdt: Watchdog driver and macros
cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not
compatible with the 8xx because it starts the watchdog HW timer at
reset and must be serviced from the very beginning including while
U-boot is executed in the firmware before relocation in RAM.
Select CONFIG_HW_WATCHDOG and make hw_watchdog_reset() visible.
Meanwhile, finalise the cleanup of arch/powerpc/cpu/mpc8xx/Kconfig by
removing the lines put in comment in that commit, and also remove
again the selection of CONFIG_MPC8xx_WATCHDOG which was removed by
that commit and brought back by mistake by commit b3134ffbd944
("watchdog: Kconfig: Sort entry alphabetically")
Note that there was an 'imply WATCHDOG' in the original commit but
it disappeared in the Kconfig alphabetical sorting, so no need to
remove it here.

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.
