[PATCH u-boot-marvell v2 0/9] More verifications for kwbimage in SPL

[Marek Behún]

From: Marek Behún <marek.behun@nic.cz>

Hello Stefan,

this is v2 of series that adds more checks for kwbimage validity and
consistency to SPL, mainly checking image data checksum.

Changes since v1:
- updated error messages as requested by Stefan
- fixed checkpatch warnings for uintN_t types (converted to preferred
  uN)
- added more checkpatch fixes

Marek

Marek Behún (4):
  arm: mvebu: spl: Print srcaddr in error message
  arm: mvebu: spl: Use preferred types u8/u16/u32 instead of uintN_t
  arm: mvebu: spl: Use IS_ENABLED() instead of #ifdef where possible
  arm: mvebu: spl: Fix 100 column exceeds

Pali Rohár (5):
  arm: mvebu: Check that kwbimage offset and blocksize are valid
  SPL: Add struct spl_boot_device parameter into
    spl_parse_board_header()
  arm: mvebu: Check that kwbimage blockid matches boot mode
  SPL: Add support for checking board / BootROM specific image types
  arm: mvebu: Check for kwbimage data checksum

[PATCH u-boot-marvell v2 1/9] arm: mvebu: Check that kwbimage offset and blocksize are valid

[Marek Behún]

From: Pali Rohár <pali@kernel.org>

There are certain restrictions for kwbimage offset and blocksize.
Validate them.

[PATCH u-boot-marvell v2 2/9] SPL: Add struct spl_boot_device parameter into spl_parse_board_header()

[Marek Behún]

From: Pali Rohár <pali@kernel.org>

Add parameter spl_boot_device to spl_parse_board_header(), which allows
the implementations to see from which device we are booting and do
boot-device-specific checks of the image header.

[PATCH u-boot-marvell v2 3/9] arm: mvebu: Check that kwbimage blockid matches boot mode

[Marek Behún]

From: Pali Rohár <pali@kernel.org>

Each boot mode has its own kwbimage specified by blockid. So check that
kwbimage is valid by blockid.

[PATCH u-boot-marvell v2 4/9] SPL: Add support for checking board / BootROM specific image types

[Marek Behún]

From: Pali Rohár <pali@kernel.org>

Commit 9baab60b8054 ("SPL: Add support for parsing board / BootROM specific
image types") added support for loading board specific image types.

This commit adds support for a new weak function spl_parse_board_header()
which is called after loading boot image. Board may implement this function
for checking if loaded board specific image is valid.

[PATCH u-boot-marvell v2 8/9] arm: mvebu: spl: Use IS_ENABLED() instead of #ifdef where possible

[Marek Behún]

From: Marek Behún <marek.behun@nic.cz>

Use the preferred
  if (IS_ENABLED(X))
instead of
  #ifdef X
where possible.

There are still places where this is not possible or is more complicated
to convert in this file. Leave those be for now.

As written in comment above there is no SerDes and DDR3 support for
Armada 375 and therefore there is no serdes_phy_config() or ddr3_init()
function. So this code needs not to be compiled at all and usage of
#ifdef is correct here.

#ifdefs are almost never correct in C-files, for the parts of the code
they guard isn't put through syntactic analysis, and can therefore
contain bugs which we are not warned about.

Using if (IS_ENABLED()) almost never producess a different binary,
because the code is optimized away.

Maybe change message to "ERROR: Wrong srcaddr (%u) in SATA kwbimage" for
consistency with other newly added error messages in this patch series?

There is no function serdes_phy_config() for Armada 375, so if you put
it outside of #ifdef you will get compile error.

The function is always declared in
  arch/arm/mach-mvebu/include/mach/cpu.h
regardless of architecture.

Thus an error will be raised only when linking, and the compliation was
done with -O0, which I don't think anyone does.

Anyway, if we want to support -O0, this can and should be solved via
defining serdes_phy_config() as empty static inline function in the
cpu.h header, guarded by #ifdef. In header files #ifdefs are allowed,
in this manner:
  #if X
  declare function
  #else
  define that function as empty static inline
  #endif

So if you think we should support -O0, I can do this.

But the #ifdefs should really go away from real C code, that is the way
both Linux and U-Boot are trying to go for the last couple of years, if
I understand it correctly.

Yes, the #ifdef's really should be avoided if possible. So *if* your
patch above does not generate any build issues, then I don't see any
problems to include it. I personally don't think that we need to support
-O0 builds.

db-88f6720_defconfig builds without issue (armada 375). And it builds the
relevant file, spl/arch/arm/mach-mvebu/spl.o.

-O0 is useful for debugging purposes, it generates more readable
assembler code.

Anyway, the issue here is that those two functions are not defined and
implemented for armada 375 soc. #ifdef is here to selectively do not
compile code which is not implemented on armada 375. And this cannot be
done by normal if(). The reason that it currently works is just because
gcc compiler does not do all checks before doing optimizations and so it
currently does generate any errors or warnings. But this is just
undefined behavior and like any other undefined behavior it may change
in some future version of gcc (or changing compiler to some other).

This approach with converting correct #ifdef to if() with undefined
behavior just hides the real issue that those two functions are not
defined and implemented for all mvebu platforms.

Why not rather to define these two functions are empty static inline
stubs with big comment that they are missing? I think this is proper
solution as it does not depends on undefined behavior of compiler and
linker, supports also -O0 and removes that #ifdef in spl.c file.

Compiler cannot currently check this, only linker, because the function
is always declared in mvebu's cpu.h.

See https://lore.kernel.org/u-boot/20211214134536.2baeb2a0@thinkpad/
where I also proposed empty static inline implementations for non-A375
platforms, but Stefan thinks it's not an issue currently, because it
does not cause any regressions, I guess. U-Boot's build system
currently does not allow for -O0, you can choose only -O2 or -Os.

We can always add empty static inline implementations into mvebu's
cpu.h when it becomes an issue, or you can send a patch now, if you
want a completely perfect code ASAP.

But note that for that you'll need to check other functions there, as
well. (If you look at
  https://source.denx.de/u-boot/u-boot/-/blob/master/arch/arm/mach-mvebu/include/mach/cpu.h
there are functions declared, without guarding #ifs, for all mvebu
platforms: A3k, A7k, A37x and A38x.)

And btw, I just tried forcing -O0, and didn't even get to SPL compiling
stage. U-Boot proper didn't failed to link with:

   undefined reference to `of_read_u32_index'
   undefined reference to `of_read_u64'
   undefined reference to `of_find_property'
   undefined reference to `of_read_u32_array'
   undefined reference to `of_device_is_available'
   undefined reference to `of_get_parent'
   undefined reference to `of_get_address'
   undefined reference to `of_n_size_cells'
   undefined reference to `of_translate_address'
   undefined reference to `of_n_addr_cells'
   undefined reference to `of_property_match_string'
   undefined reference to `of_parse_phandle_with_args'
   undefined reference to `of_count_phandle_with_args'
   undefined reference to `of_find_node_opts_by_path'
   undefined reference to `of_get_property'
   undefined reference to `of_device_is_available'
   undefined reference to `of_get_property'
   undefined reference to `of_simple_addr_cells'
   undefined reference to `of_simple_size_cells'
   undefined reference to `of_device_is_compatible'
   undefined reference to `of_get_stdout'

Since no-one noticed this till now, I would bet the reality is that -O0
really isn't done, and if someone really needs it, they will have to
fix other things as well.

Also with -O0 I think SPL would be too big so you won't be able to test
it anyway. Although you could study generated and linked assembler
code, but why would you do that? You can just disassemble the object
file.
