[PATCH v2 0/3] Simplify image size checks

[Philip Oberfichtner]

Depends on:
	- https://patchwork.ozlabs.org/project/uboot/patch/20250807075653.356088-2-pro@denx.de/
	- https://patchwork.ozlabs.org/project/uboot/patch/20250807075653.356088-3-pro@denx.de/

This patch series intends to simplify the image size checks, which currently
exist in multiple flavours:

	CONFIG_HAS_BOARD_SIZE_LIMIT
	CONFIG_BOARD_SIZE_LIMIT
	CONFIG_UBOOT_WITH_SPL_SIZE_LIMIT
	CONFIG_SPL_SIZE_LIMIT
	CONFIG_SPL_SIZE_LIMIT_SUBTRACT_GD
	CONFIG_SPL_SIZE_LIMIT_SUBTRACT_MALLOC
	CONFIG_SPL_SIZE_LIMIT_PROVIDE_STACK
	CONFIG_TPL_SIZE_LIMIT
	CONFIG_VPL_SIZE_LIMIT

After this series, we would have
	- Less code duplication in the toplevel Makefile
	- Consistent logic for all the different CONFIGS
	- All related options in one place

Changes in v2:
	- Rebase on current master
	- Rebase on my pending mips patch series (linked above)
	- Incorporated Heinrich's Review

Philip Oberfichtner (3):
  Image size checks: Remove HAS_BOARD_SIZE_LIMIT
  Image size checks: Move all configs in one place
  Image size checks: Simplify help text

[PATCH v2 1/3] Image size checks: Remove HAS_BOARD_SIZE_LIMIT

[Philip Oberfichtner]

CONFIG_HAS_BOARD_SIZE_LIMIT is obsolete, if we interpret the value
"zero" as "unlimited". This is exactly how all the other
CONFIG_XXX_SIZE_LIMITs work.

Note that we drop the "depends on !COMPILE_TEST" without replacement.
The rationale is explained here:
7adb9b03a64 (Kconfig: Test for !COMPILE_TEST in some locations).

Signed-off-by: Philip Oberfichtner <pro@denx.de>

Notes:
    Changes in v2:
    	- Move "default 0" to the very end
    	- Rebase on current master

This sentence makes no sense. Is the variable not obsolete if its value 
is non-zero ?

This looks wrong, no board size limit does not imply EFI anything.

And use some common sense and reduce the CC list.

This is phrased oddly, yes. How about:
By making the code treat a size limit of 0 as unlimited we no longer
need to guard asking about having a size limit on the platform.

This is however preserving the existing functionality. Saying that no,
we shouldn't enable EFI debug support by default in any cases would be a
stand alone patch.

0 shouldn't mean unlimited, that is just fragile ...

... fragile and confusing. HAS_BOARD_SIZE_LIMIT is at least clear about 
what it does.

That's a standard unix thing? ulimit -c 0 is unlimited.

This is a really bad argument, because then the counter-argument is, 
that size = 0 is also a valid size and it shouldn't be conflated with 
SIZE_LIMIT validity.

My take on this is, don't conflate size-limit "enabled/disabled" with 
size-limit "value" , these are two separate config options. Mixing them 
is not helping.

I still think it's fine, but it's not worth arguing further over, and we
can just make sure to gate all of the symbols rather than 0-is-disabled.

The idea of treating a size limit of zero as unlimited has been common
practice in mainline U-Boot since 2019, where CONFIG_SPL_SIZE_LIMIT has
been introduced. The same logic has later been applied to TPL and VPL
size limits.

If we want to consistently stick to the HAS_*_SIZE_LIMIT approach, we'd
have to introduce four extra Kconfig options alongside
HAS_BOARD_SIZE_LIMIT:

	CONFIG_HAS_UBOOT_WITH_SPL_SIZE_LIMIT
	CONFIG_HAS_SPL_SIZE_LIMIT
	CONFIG_HAS_TPL_SIZE_LIMIT
	CONFIG_HAS_VPL_SIZE_LIMIT


Furthermore, the extra lines of code in the toplevel Makefile, which
could otherwise be removed:

	ifneq ($(CONFIG_BOARD_SIZE_LIMIT),)
	BOARD_SIZE_CHECK= @ $(call size_check,$@,$(CONFIG_BOARD_SIZE_LIMIT))
	else
	BOARD_SIZE_CHECK =
	endif

	ifneq ($(CONFIG_HAS_UBOOT_WITH_SPL_SIZE_LIMIT),0x0)
	UBOOT_WITH_SPL_SIZE_CHECK = @$(call size_check,$@,$(CONFIG_UBOOT_WITH_SPL_SIZE_LIMIT)
	else
	UBOOT_WITH_SPL_SIZE_CHECK =
	endif

	ifneq ($(CONFIG_SPL_SIZE_LIMIT),0x0)
	SPL_SIZE_CHECK = @$(call size_check,$@,$$(tools/spl_size_limit))
	else
	SPL_SIZE_CHECK =
	endif

	ifneq ($(CONFIG_TPL_SIZE_LIMIT),0x0)
	TPL_SIZE_CHECK = @$(call size_check,$@,$(CONFIG_TPL_SIZE_LIMIT))
	else
	TPL_SIZE_CHECK =
	endif

	ifneq ($(CONFIG_VPL_SIZE_LIMIT),0x0)
	VPL_SIZE_CHECK = @$(call size_check,$@,$(CONFIG_VPL_SIZE_LIMIT))
	else
	VPL_SIZE_CHECK =
	endif


Is it really worth adding this much of extra code?

Philip

Hi Marek,

You criticised the patch in its current form. Nevertheless, I'm left in
the dark which outcome you would approve of.

If I'm not missing out on something, we have three options:

(a) Use the value zero to disable size limits, as this series proposes
(b) Use XXX_HAS_SIZE_LIMIT consistently, implying a lot of extra code
(c) Maintain the status quo, which is 80% of (a) and 20% of (b)


I'd like to bring this thing to an end, finally. So could you please
position yourself?

Best regards,
Philip

That still does not make it the correct approach.

This is fine by me.

This code is already in the U-Boot Makefile .

Maybe tools/spl_size_limit.c could be somehow extended to deduplicate 
the above ?

> Is it really worth adding this much of extra code?
Yes, because 0 does not mean unlimited .

UBOOT_WITH_SPL_SIZE_LIMIT will be required for my currently pending mips
board support, see here:
https://patchwork.ozlabs.org/project/uboot/list/?series=468232.

In the next version, I'll include all size limit related patches in THIS
series. Sorry for the confusion.

Do it the other way around, finalize this series as a clean up only, and 
do additional features in follow up patches .

Wouldn't the CC list naturally be large for a patch changing 43

[PATCH v2 3/3] Image size checks: Simplify help text

[Philip Oberfichtner]

For coherency, use the same help text for all related size checks
options. Furthermore, simplify the depends-on logic.

This makes the description less accurate, sorry, NAK.

What about using just the first half:

	Maximum size of the U-Boot image. When defined, the build system
	checks that the actual size does not exceed it.
	[plus/minus treatment of the value zero]

And dropping the remainder "This does not include ..."?

I think the hint on the separate options would be unnecessary, if they
are placed placed just below.

Best regards,
Philip

If you want to make two unrelated changes, please, create two separate
patches.

Why would removing the SPL/TPL clarification be any improvement ?

This statement used to be sensible, as long as all those size limit
options were spread out over many different Kconfig files. Now having
them all together in on place, I find it rather obvious.

Furthermore, if you want maximum accuracy, you'd have to extend the text
to also include a reference to VPL and u-boot-with-spl config options.
But even then, you still won't be able to fully grasp the functioning of
BOARD_SIZE_LIMIT without consulting the Makefile.

Well, that's what I thought. If you don't agree, I'm also fine to just
leave it as is.
