[PATCH 01/16] arm: stm32mp: update dependency for STM32_ETZPC

[PATCH 01/16] arm: stm32mp: update dependency for STM32_ETZPC

[Patrick Delaunay]

Correct the dependency for STM32 ETZPC protection, linked to SOC
STM32MP identified by CONFIG_STM32MP15x and not linked to
CONFIG_TARGET_STM32MP1 (no more existing).

This patch fix an issue introduced by commit 846254888e2e ("stm32mp1:
split board and SOC support for STM32MP15x family").

[PATCH 03/16] arm: stm32mp: reset to default environment when serial# change

[Patrick Delaunay]

Serial number is first checked and, in case of mismatch, all
environment variables are reset to their default value.

This patch allows to detect that environment is saved in a removable
device, as a SD card, and reused on a other board, potentially with
incompatible variables.

[PATCH 07/16] board: stm32mp1: Keep error led ON in case of low power detection

[Patrick Delaunay]

From: Patrice Chotard <patrice.chotard@st.com>

Since commit commit dd2810851eb1 ("stm32mp1: board: support of
error led on ed1/ev1 board") the attended behavior was no more
respected in case of low power source detection on DK2.

The expected behavior is either the error LED keeps blinking for ever,
or blinks 2 or 3 times and must stay ON.

This is an unrelated and totally undocumented change.  Please split
into separate commit.

Resetting the enviropnment to the defaults means you drop all
setting sa user may have made.  This is a very bad move - as a user
I find such things completely unacceptable.  If I make any changes,
they must never ever be killed without my explicit confirmation.

I strongly advice against such a method. Please drop that.

Best regards,

What is env_ver?  Are you by chance reinventing the wheel?

The U-Boot version is stored in the environment variable "ver";
there should be no need for something similar.


Also. where is $env_ver coming from? It does not exist in mainline,
nor in any of the 3 patches that preceed this patch # 4/16 ?

This seems to be an unrelated change?  You should at least explain
why this is needed, and if it's unrelated, spilt into a separate
commit.

This change makes little sense to me/  If you want error messages,
then just turn above debug() into printf(), and be done with it.
As an additional benefit so see at once which step failed.

This is inconsistent, please use CONFIG_IS_ENABLED() everywhere
instead of #ifdef's.

If this is an error condition, you should use printf(), and not

I think this is generally a bad idea.  You should have more respect
to the intentions of your users.  If a user defines a specific
bootdelay setting in his environment, this must be respected.

I really hate vendors who believe they know better than me what I
want or what is good to me.  Please get rid of such stuff.

"bootdelay" is an environment variable that is intentionally user
definable. You must never mess with those.

Did you verify that this works like expected? We either use

Understood, I drops this patch....

I introduce this behavior after a internal request and to avoid issues during tests:

Some users use the same SD card (same rootfs) on several boards (EV1 and DK2 for example)
and the U-Boot environment is saved on this SD card. 

When an user updates U-Boot binary to use this SD card on other board but not erase the
environment file (save in ext4 file in bootfs partition), the boot can fail because the
environment is not compatible between the 2 boards.

This patch try to avoid this issue when I detect that the removable device (as SD card) is used on a
a different board (it is detected when saved serial number with different the OTP).

But I admit that can be strange/unacceptable for end-user, particularly it is only change of board
(DK2#1 => DK2#2) : the environment tuned one board #2 can't be used on board#2.

I make too many assumption on user usage and this patch can't be acceptable in arch 
(common for all board based on STM32MP15x).

The script env_check is ;
 
	env exists env_ver || env set env_ver ${ver};

	if env info -p -d -q; then env save; fi;

	if test \"$env_ver\" != \"$ver\"; then
		echo \"*** Warning: old environment ${env_ver}\";
		echo '* set default: env default -a; env save; reset';
		echo '* update current: env set env_ver ${ver}; env save';
	fi;

In the first line of the script: "env exists env_ver || env set env_ver ${ver}", so

$env_ver = $ver, before the first env_save during the first boot (second line of the script)

env_ver is only defined and used in this script to detect that current U-Boot version ($ver) and 
the version of U-Boot for last env save ($env_var) are not aligned.

I introduce this warning after debug of many issue around this kind of error, but perhaps more
a debug feature.

So if you found that it is a bad idea for upstream, I will drop this part and just to the new quiet option
To simplify the test:

env_check = " if env info -p -d -q; then env save; fi;"

Well, why would that fail on another board but not on the one that
is currently in use?  Where is the U-Boot image you are booting
from?   Not on the SDCard, too?

Well, then this is a design problem (or you may even call it a
design bug).  It has always been a bad idea to use a fixed structure
binary format if there are chances that provider (the env storage)
and consumer (U-Boot) may get out of sync.

The binary blob environment format (checksum, eventually redundancy
flag, date with a fixed total size) is inherently only compatible
with other U-Boot versions as long as redundancy and size settings
are kept the same.

If you cannot garantee this, you should use a different storage
format - for example as plain text file.  Of course you pay for
added compatibility across U-Boot configurations with the price of
reduced security (lack of checksum).

But then, normally you do not change redundancy or environment size
between U-Boot versions, so all this should be a theroretical
problem only?

You see this only as a risk - try to see it as a chance, too.
Imagine a user is trying to copy environment between systems.  Why
would you want to stop him?

Any incompatibility issues can reliably be avoided when using binary
blob format, as then you will get a checksum error, and the
incorrect copy is ignored.

All such automatical "env save" actions somewhere in the code give
me the creeps.  I've seen too often that they did things I nver
intended to do or would have accepted if I had a chance to decide.

Use extremely careful, please.

From a user point of view, it's me who owns the environment, and
nobody should mess with my data without me confirming it.

Sure,

In this case, the command "env info -d" tests if the default environment is currently used,
So the user have never updated and saved the environment.

In this case and if the persistent storage is available (option -p), the script "env_check" save the environment.

PS: I take the initial idea from ./include/configs/opos6uldev.h and ./include/configs/apf27.h
 
> From a user point of view, it's me who owns the environment, and nobody should
> mess with my data without me confirming it.

As the save action is performed only when default environment is used, it is done before 
any user modification so I don't think that it is annoying for user.

I also kept the call this feature only in the ST specific bootcmd_stm32mp to allow customization for users or other boards.
(I prefer to don't add it in board_late_init() as it is done in board/intel/edison/edison.c)

The purpose of the "env save" is just to avoid a "Warning" during the boot, 
until the first user action and "env save" command:

Loading Environment from MMC... *** Warning - bad CRC, using default environment

The content of environment before and after the save is identical: it is the default one.
but if it is too aggressive I can kept it for downstream.

Marek do you have a opinion: it is acceptable for DH SOM using STM32MP15x SOC?

In this patch, I try to display error as soon as console is available
(after preloader_console_init) , if after one driver initialization
(clk, reset, pincontrol) failing.

Change debug to printf only works only if CONFIG_DEBUG_UART 
is activated (not by default) and board_debug_uart_init() exist to configure
the needed UART TX pins.

At least I need to remove the return and change them to hang() to interrupt SPL
execution if one probe failed to detect issue

I spent some time for this kind of issue: clock probe failed without any trace.

Maybe you can remember an error code so you can tell the user which
of the steps failed? That would be more useful, then.

After check, I agree with you first comment.

Because console over serial can work only if the driver required for uart driver (clk, reset, pincontrol) can probe.

So CONFIG_DEBUG_UART is mandatory to identify the  failing step and debug() is enough in this case.

In fact my initial issue was only the simple return (and SPL boot continue) 
when a error was detected: I replace them by hang() calls.

That simplify the implementation in V2:
