[U-Boot] [PATCH v4 0/4] configs: rk3288: Tinker Board SPL file must fit into 32 KiB

[U-Boot] [PATCH v4 0/4] configs: rk3288: Tinker Board SPL file must fit into 32 KiB

[Heinrich Schuchardt]

The SPL image for the Tinker Board has to fit into 32 KiB. This includes
up to 2 KiB for the file header.

A new configuration variable CONFIG_SPL_SIZE_LIMIT is introduced to define
the board specific limit.

A common Makefile function is used for this test and the test against
CONFIG_BOARD_SIZE_LIMIT.

Move the board size check from arch/arm/mach-imx/Makefile to Makefile.

v4:
	use a common function for all size checks in the Makefiles

[U-Boot] [PATCH v4 1/4] Makefile: reusable function for BOARD_SIZE_CHECK

[Heinrich Schuchardt]

Carve out function size_check from macro BOARD_SIZE_CHECK. This will allow
us to reuse the function for other file size checks.

Depending on the value of CONFIG_BOARD_SIZE_LIMIT an error like the
following is thrown:

u-boot-dtb.img exceeds file size limit:
  limit:  409516 bytes
  actual: 444346 bytes

[U-Boot] [PATCH v4 2/4] imx: move BOARD_SIZE_CHECK to main Makefile

[Heinrich Schuchardt]

We currently have duplicate definitions for BOARD_SIZE_CHECK in Makefile
and arch/arm/mach-imx/Makefile.

Move the board size check from arch/arm/mach-imx/Makefile to Makefile.

Depending on the value of CONFIG_BOARD_SIZE_LIMIT an error like an error
like the following is thrown:

Hello Stefano, hello Fabio,

there have been some comments to 0/4 indicating that the first patch of
the series should be reworked.

But I think this one is worth merging on it own. Could you, please,
review it and if ok add it to your IMX repository.

Best regards

Heinrich

[U-Boot] [PATCH v4 3/4] configs: define CONFIG_SPL_SIZE_LIMIT

[Heinrich Schuchardt]

A new configuration variable CONFIG_SPL_SIZE_LIMIT is introduced to define
the board specific maximum size for the SPL file.

Use Makefile function size_check() to implement the test.

Depending on the size of CONFIG_SPL_SIZE_LIMIT an error like the following
is thrown:

spl/u-boot-spl.bin exceeds file size limit:
  limit:  30720 bytes
  actual: 33426 bytes
  excess: 2706 bytes

Just tested this on mx6sabresd_defconfig, where the SPL size limit is
68 * 1024, so I passed:

CONFIG_SPL_SIZE_LIMIT=69632

but SPL builds without error and the generated size is 76800.

Any ideas why CONFIG_SPL_SIZE_LIMIT did not catch the SPL size
overflow for mx6sabresd_defconfig?

Thanks

So, I hit this too.  SPL_SIZE_LIMIT is hex, not int.  Or rather, Simon's
patch changes it from int to hex, which, yeah, that's wrong.  Thanks for
the report, patch coming up!

I'm sorry you weren't Cc'd on Simon's thread where we're trying to
improve the size check stuff to be generic enough to use everywhere.  We
can't generically use a shell script as we need to know some processed
values too.  I don't know if Simon got to the point of writing a C based
helper to use or not.

Hello Tom,

could you, please, provide a link to the thread.

Is the test prior to my patch incorrect? Or do you want to imply that
after my patch we get different results?

Best regards

Heinrich

The problem is that I don't want to make wider use of the shell checking
notion.  It's not as complete as we'd like and can't be used on as many
platforms as need it either, due to needing cpp to actually determine
values in some cases.

Yes, the patch by Simon G. is similiar to my patch series. What his
patch does not address is the duplicate coding for checking *.imx files.
My idea has been to put all tests into the main Makefile to avoid
problems with variable substitutions.

It is unclear to me what you mean by: "It's not as complete as we'd
like" and where you see a need for "cpp to actually determine values".

I would not be able to provide a better patch without understanding your
view on the requirements.

Best regards

Heinrich

Right, I should have included you, Heinrich, sorry.

No, unfortunately, I haven't found the time to work on the C based 
approach, yet.

To sum it up, Heinrich, the issue was that for socfpga gen5, we're 
approaching the 64KiB total limit for SPL. That includes all regions we 
can check via CONFIG_SPL_MAX_FOOTPRINT (e.g. text, data, bss) plus 
devicetree, early malloc, global data and initial stack.

My approach would have been much like your check (which by the way is 
better than mine in that the check stays in main Makefile), but the size 
limit needs to include those items I've mentioned above. So while I 
could add a Kconfig based total size, I would need to subtract gd, 
malloc area and reserved stack size to get the SPL_SIZE_LIMIT value.

The problem I see here is that this is a different size limit to the one 
you want to check. I need "SRAM_SIZE - x - y - z" while you need 
"LOAD_LIMIT", which is constant.

Maybe we could start with your limit and then add bool config options 
like "SPL_SIZE_LIMIT_SUBTRACT_GD", "SPL_SIZE_LIMIT_SUBTRACT_MALLOC_F" 
and "SPL_SIZE_LIMIT_SUBTRACT_STACK_SIZE" that could then be used by a C 
program to help the size check.

Regards,
Simon

32KB is the limit of SPL size, not SPL image size, does not include 2KB
header.

There is already CONFIG_SPL_MAX_SIZE for the SPL size limit, isn't it?
I don't understand  why we need new variable.

SPL_MAX_SIZE is used to set CONFIG_SPL_PAD_TO if CONFIG_SPL_PAD_TO is
not defined. If CONFIG_SPL_PAD_TO is defined it specifies the maximum
value of CONFIG_SPL_PAD_TO. So in case CONFIG_SPL_PAD_TO is not defined
SPL_MAX_SIZE does not specify a maximum size but a minimum one.

It is unclear to me why Benoît in 6113d3f27ca ("Makefile: Change
CONFIG_SPL_PAD_TO to image offset") chose this design. Entangling the
variables in this way does not provide a clean design.

The check

#if defined(IMAGE_MAX_SIZE)
ASSERT(__image_copy_end - __image_copy_start < (IMAGE_MAX_SIZE), \
        "SPL image too big");
#endif

in arch/arm/cpu/u-boot-spl.lds neither considers the size of the device
tree nor of the BSS section. So@least for Rockchip SOCs it is
checking a measure that is not directly related to the image size
created by `mkimage -T rksd`.

If CONFIG_SPL_PAD_TO is defined and non-zero, CONFIG_SPL_MAX_SIZE
specifies the _minimum_ value of CONFIG_SPL_PAD_TO.

> So in case CONFIG_SPL_PAD_TO is not defined
> SPL_MAX_SIZE does not specify a maximum size but a minimum one.

CONFIG_SPL_MAX_SIZE specifies a minimum value for CONFIG_SPL_PAD_TO,
but a maximum size for the SPL.

> It is unclear to me why Benoît in 6113d3f27ca ("Makefile: Change
> CONFIG_SPL_PAD_TO to image offset") chose this design. Entangling the

Everything is explained in this thread:
https://lists.denx.de/pipermail/u-boot/2013-February/146851.html

These two variables coexisted before this change. They have different
purposes, but they are related, so they cannot take any values
independently of each other.

The purpose of CONFIG_SPL_MAX_SIZE is not to define default or minimum
values for CONFIG_SPL_PAD_TO, but only what its name says, i.e. to
define the maximum SPL size.

After the SPL, there may be a gap, then a payload appended to the
image. The purpose of CONFIG_SPL_PAD_TO is to define the image offset
of the payload, if any. CONFIG_SPL_PAD_TO can be 0 if the payload can
always be appended to the SPL without any gap.

Therefore, the SPL must fit inside CONFIG_SPL_MAX_SIZE, and
CONFIG_SPL_MAX_SIZE must fit inside CONFIG_SPL_PAD_TO if the latter is
non-zero.

[...]

Best regards,
Benoît

Has anything from this series been applied? I now have a working patch 
that applies on top of this and adds a full SPL SRAM size check 
(including HEAP, GD and stack; via a host tool) which works for socfpga 
(as an example of a platform where SPL binary is loaded to limited SRAM).

Actually, my patch would replace your patch 3/4 but build on 1/4 (2/4 
and 4/4 are arch-specific).

How should we proceed here? I could send a series including your 1/4, or 
I could send a series completely building on this series, at the 
downside of more or less reverting your 2/4.

Simon

What I would like to see is i.MX (and rockchip) converted to use your
new test as well (also, yay!  Thanks for following up on that!) and we
drop the existing check here.

Ok, so while I cannot really help on i.MX and rockchip, why don't you 
accept this series from Heinrich and I'll send my patch as followup? 
Then we can discuss this with i.MX and rockchip maintainers.
