[PATCH V4 0/8] arm64: binman: use binman symbols for imx

[PATCH V4 0/8] arm64: binman: use binman symbols for imx

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

V4:
 Fix three boards build failure

V3:
 Add R-b/T-b
 Fix build warning

V2:
 resolve some CI failure
 include patch 7

binman symbol is a good feature, but only used on X86 for now. This patchset
is to use it for i.MX8M platform.

The current imx8m ddr phy firmware consumes lots of space, because we pad
them to the largest 32KB and 16KB for IMEM and DMEM.

With this patchset we use binman symbols to get firmware location and size,
we could save near 36KB with i.MX8MP-EVK.

Please help check and test

[PATCH V4 1/8] spl: guard u_boot_any with X86

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

set the symbol as weak not work if LTO is enabled. Since u_boot_any is
only used on X86 for now, so guard it with X86, otherwise build break
if we use BINMAN_SYMBOLS on i.MX.

I think we long term need to figure this out and address it so LTO
works.  But for now can you please guard this with a test on LTO
instead, so it's clear where the problem is?

Sorry, I could not get your point about guard with a test on LTO.

Actually binman weak symbol will report a warning log if there is no u_boot_any
binman symbol. Since only X86 use it, I guard with X86.

Thanks,

Why are you mentioning LTO in the commit message?  When I read the
commit message it sounds like you're saying the problem is that LTO
doesn't like how this symbol is handled, but if LTO was disabled,
everything would be fine.  If it's not LTO-related, please re-word the
message instead.

It looks like we should be able to change things in common/spl/spl.c to:

    #if CONFIG_IS_ENABLED(BINMAN_SYMBOLS)
    /* See spl.h for information about this */
    binman_sym_declare_optional(ulong, u_boot_any, image_pos);
    binman_sym_declare_optional(ulong, u_boot_any, size);
    #endif

which would mark the symbol as 'weak' and turn the error into a warning
on the binman side. But that is somehow being undone by LTO.

I'm trying to build for imx8mm-beacon with that change instead of this
patch. With CONFIG_LTO=y, build fails and spl/u-boot-spl.sym has:

> 00000000007fbe28 l     O .binman_sym	0000000000000008 _binman_u_boot_any_prop_image_pos

Looks like the size symbol is optimized out. With CONFIG_LTO unset, the
build succeeds and the same file has:

> 00000000007fe90c  w    O .binman_sym	0000000000000008 _binman_u_boot_any_prop_image_pos
> 00000000007fe904  w    O .binman_sym	0000000000000008 _binman_u_boot_any_prop_size

I don't know much about linking stuff, so this is as deep as I could dig...

So, looking at binman_sym_declare_optional we tell the linker that it's
weak and might even be unused.  LTO gets very aggressive about finding
things that aren't used in the resulting binary and discarding them.
Typically we have the problem of a function that is used but it's hard
for LTO to see it, so we give it the "used" attribute.  But for
something we're already saying is "unused" this would be wrong.  So why
do we mark things as unused here?  I assume it's marked weak as it could
be overridden at link time by a definition elsewhere.

I don't know, but the GCC manual says marking things 'unused' will
suppress a warning if the variable is actually unused. I guess binman
symbols may become unused due to some other config options being unset,
and it's done for those cases?

I think the optional symbols are marked weak just to signal the python
side that they are optional. If I understand it right, binman:

1. Packs an image using the finalized 'spl/u-boot-spl.bin'
2. Figures out the image-pos and size values of every entry
3. Inspects the 'spl/u-boot-spl' ELF file for declared binman symbols
4. Raises an error if any non-'weak' symbol's value is undetermined
5. Updates the u-boot-spl.bin (in memory) with the calculated values
6. Recreates the final image based on that updated bin file.

Thanks for the detailed sharing. Yes, this is the issue I try to work around. Some
i.MX boards has LTO set, this leads me to use X86 as an extra guard.

Thanks,

Sorry, I could reword the commit message, but currently I have no better
idea to address the issue unless use X86 as a guard in the code as this
patch does. If you agree the code in this patch, I could reword commit msg
and send v5.

Well, lets see what Alper says in the other part of the thread.  I'd
really like to solve this not work around this.  But I'll take
documenting the problem for the person that has X86 && LTO as good
enough for the moment.

Alternatively, I think we can decide that all binman symbols are
optional, and not raise an error when we can't find a value for them.
They are de-facto optional anyway: people can use the non-binman-image
build artifacts (which binman doesn't update wrt. symbols), thus the
code that uses binman symbols should assume their values can be missing.

If I apply the series without this patch and try to build imx8mm-beacon,
I get the following error, and I'm assuming that's what you're trying to
solve here:

    binman: Section '/binman/u-boot-spl-ddr': \
      Symbol '_binman_u_boot_any_prop_image_pos' in entry \
      '/binman/u-boot-spl-ddr/u-boot-spl/u-boot-spl-nodtb': \
      Entry 'u-boot-any' not found in list (...)

The immediate cause for this is that your 'u-boot-spl-ddr' image has no
'u-boot'-like entry, meaning there's no reasonable value to write into
the non-optional 'u_boot_any' symbol.

(I think it might be OK to make this symbol optional, but LTO breaks
that as you found out. The rest of this email is about my thoughts
before I realized the LTO problem, but they're still relevant.)


It looks like binman images were designed to be monolithic instead of
modular, and it's assumed you'd have one fully-specified image for your
'flash.bin' where 'u-boot-spl' would know about (for example) a 'u-boot'
in a FIT entry. (I would like things to be modular eventually, though).

I tried to merge things into a single binman image, but mkimage is
trying to read 'u-boot-spl-ddr.bin' which would no longer exist. I see
this is because it's specified in 'spl/u-boot-spl.cfgout' as a LOADER
file in a later patch.

Maybe 'imx8mimage.c' can be changed to use mkimage's -d argument as the
LOADER instead? That's how binman passes the input data to mkimage, but
that seems to be ignored in this case. Then we can merge things into a
single image which will be able to set the 'u_boot_any' symbols without
error.

Otherwise, the mkimage file reading error can be solved by creating a
new binman 'imx8m-image' entry type that creates the 'cfgout' and calls
mkimage with it. (Binman images would still need to be merged).

[PATCH V4 2/8] arm: dts: imx8m: update binman ddr firmware node name

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

We are migrating to use BINMAN SYMBOLS, the current name is not
a valid binman type, so update to use blob-ext@[1,2,3,4].

I think descriptive entry names are better in general, so I prefer the
old names to a bunch of 'blob-ext's. Symbol resolution is done using the
entry names anyway, I don't see why this change would be necessary.

In any case, the names and labels should be consistent across the
different dts files, assuming the blobs have the same purpose / meaning.
I see that labels starting with digits cause a dtc parse error, so the
entries could be `imem_1d: imem-1d { ... };` and so on.

Also, the blobs essentially look the same to me aside from their
filenames, just duplicated over different imx8m* variants and boards.
Maybe binman parts could be unified into a single dtsi file later on?
(Filename differences can be handled by new 'blob_named_by_arg's btw.)

Maybe this could be done for other imximage*.cfg files as well?

Yes, there are follow up patches to clean up the cfg files, this patch
is for binman and avoid build break for these two boards.

Thanks,

[PATCH V4 4/8] armv8: u-boot-spl.lds: mark __image_copy_start as symbol

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

In arch/arm/lib/sections.c there is below code:
char __image_copy_start[0] __section(".__image_copy_start");
But actually 'objdump -t spl/u-boot-spl' not able to find out
symbol '__image_copy_start' for binman update image-pos/size.

So update link file

[PATCH V4 5/8] tools: binman: section: replace @ with -

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

In arch/arm/dts/imx8mp-u-boot.dtsi, there are blob-ext@1, blob-ext@2 and
etc which is for packing ddr phy firmware. However we could not declare
symbol name such as 'binman_sym_declare(ulong, blob_ext@1, image_pos)',
because '@' is not allowed, so we choose to declare the symbol
'binman_sym_declare(ulong, blob_ext_1, image_pos);' with '@' replaced with

This shouldn't be necessary if you keep the old names for the binman
entries and use `binman_sym_declare(ulong, imem_1d, image_pos);` etc.
for the symbols.

The correct place to do this would be LookupSymbol() in
binman/etype/section.py, but I'm not convinced this should be done at
all. I'd say if an entry is important enough to have a symbol for it, it
should have a unique, descriptive, non-@ name.

No, as I replied in the other mail, imem_1d is not a binman type.

Since blob_ext@[1,2,3] is used, this is to replace and generate symbols as
blob_ext_[1,2,3]

[PATCH V4 6/8] ddr: imx8m: helper: load ddr firmware according to binman symbols

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

By reading binman symbols, we no need hard coded IMEM_LEN/DMEM_LEN after
we update the binman dtsi to drop 0x8000/0x4000 length for the firmware.

And that could save binary size for many KBs.

This overwrites the values from binman symbols, which looks wrong to me.
I think this line should appear before the if block.

It does not matter actually. Put it before if block is ok.

[PATCH V4 7/8] arm: dts: imx8m: shrink ddr firmware size to actual file size

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

After we switch to use BINMAN_SYMBOLS, there is no need to pad
the file size to 0x8000 and 0x4000. After we use BINMAN_SYMBOLS,
the u-boot-spl-ddr.bin shrink about 36KB with i.MX8MP-EVK.

Tested-by: Tim Harvey <tharvey@gateworks.com> #imx8m[m,n,p]-venice

Probably can be done for 'imx8mn-bsh-smm-s2-u-boot-common.dtsi' as well.

[PATCH V4 8/8] binman_sym: guard with CONFIG_SPL_BINMAN_SYMBOLS

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

There is case that CONFIG_BINMAN is defined, but
CONFIG_SPL_BINMAN_SYMBOLS is not defined. In that case, there will be
build failure. So use CONFIG_SPL_BINMAN_SYMBOLS to guard the macros, and
define CONFIG_SPL_BINMAN_SYMBOLS in binman syms test.

I guess they should be CONFIG_IS_ENABLED(BINMAN_SYMBOLS) instead, as
there's also a CONFIG_TPL_BINMAN_SYMBOLS.

No. CONFIG_IS_ENABLED not work, because there is no defconfig generated.
