Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
This series implements this, allowing binaries within the image to become
aware of each other without any significant run-time overhead.
It can be used for:
- SPL jumping to the correct location for U-Boot
- SPL finding an FPGA image to program
- U-Boot locating some configuration data (e.g. serial #) in the image
A way to handle this with binman was requested by Marek Vasut some weeks
ago.
As a demonstration, this converts Tegra to use binman to find U-Boot from
within SPL.

To: u-boot
In some cases we need to read symbols from U-Boot. At present we have a
a few cases which does this via 'nm' and 'grep'.
It is better to use objdump since that tells us the size of the symbols
and also whether it is weak or not.
Add a new module which reads ELF information from files. Update existing
uses of 'nm' to use this module.

For testing we need to build some ELF files containing binman symbols. Add
these to the Makefile and check in the binaries:
u_boot_binman_syms - normal, valid ELF file
u_boot_binman_syms_bad - missing the __image_copy_start symbol
u_boot_binman_syms_size - has a binman symbol with an invalid size

From: Simon Glass @ 2017-11-14 1:54 UTC (permalink / raw)
To: u-boot
This is only 3 bytes long which is not enough to hold two symbol values,
needed to test the binman symbols feature. Increase it to 15 bytes.
Using very small regions is useful since we can easily compare them in
tests and errors are fairly easy to diagnose.

The elf module can provide some debugging information to assist with
figuring out what is going wrong. This is also useful in tests. Update the
-D option so that it is passed through to tests as well.

To: u-boot
Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
binman_sym_declare(unsigned long, u_boot_spl, pos);
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:
ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos);
This assigns the variable u_boot_pos to the position of SPL in the image.

This area of the image contains symbols whose values are filled in by
binman. If this feature is not used, the table is empty.
Add this to the ARM SPL link script.

Allow SPL to access binman symbols and use this to get the address of
U-Boot. This falls back to CONFIG_SYS_TEXT_BASE if the binman symbol
is not available.

SPL supports reading U-Boot from a RAM location. At present this is
hard-coded to the U-Boot text base address. Use binman to allow this to
come from the image file, if binman is used.

+--------------------------------------------

+Binman assembles images and determines where each entry is placed in the image.
+This information may be useful to U-Boot at run time. For example, in SPL it
+is useful to be able to find the location of U-Boot so that it can be executed

+Binman allows you to declare symbols in the SPL image which are filled in

+
+ binman_sym_declare(ulong, u_boot_any, pos);
+
+declares a ulong value which will be assigned to the position of any U-Boot
+image (u-boot.bin, u-boot.img, u-boot-nodtb.bin) that is present in the image.
+You can access this value with something like:
+
+ ulong u_boot_pos = binman_sym(ulong, u_boot_any, pos);
+
+Thus u_boot_pos will be set to the position of U-Boot in memory, assuming that
+the whole image has been loaded, or is available in flash. You can then jump to
+that address to start U-Boot.
+
+At present this feature is only supported in SPL. In principle it is possible

Update tegra to use binman for image creation. This still includes the
current Makefile logic, but a later patch will remove this. Three output
files are created, all of which combine
SPL and U-Boot:
u-boot-tegra.bin - standard image
u-boot-dtb-tegra.bin - same as u-boot-tegra.bin
u-boot-nodtb - includes U-Boot without the appended device tree
The latter is useful for build systems where the device is appended later,
perhaps after being modified.

I assume that last file is u-boot-nodtb-tegra.bin?
If this series doesn't change the set of binaries produced by the build
system (add/drop/rename), then I'm fine with it.
For the record, I know of tools that use the following files, at least:
u-boot (ELF)
u-boot.bin
u-boot.dtb
u-boot-dtb.bin
u-boot-nodtb-tegra.bin
u-boot-dtb-tegra.bin

OK, then I suppose we need them all. I was hoping to drop one of the
special tegra ones, but it seems like they are all used.

SPL supports reading U-Boot from a RAM location. At present this is
hard-coded to the U-Boot text base address. Use binman to allow this to
come from the image file, if binman is used.

Allow SPL to access binman symbols and use this to get the address of
U-Boot. This falls back to CONFIG_SYS_TEXT_BASE if the binman symbol
is not available.

Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
binman_sym_declare(unsigned long, u_boot_spl, pos);
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:
ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos);
This assigns the variable u_boot_pos to the position of SPL in the image.

This is only 3 bytes long which is not enough to hold two symbol values,
needed to test the binman symbols feature. Increase it to 15 bytes.
Using very small regions is useful since we can easily compare them in
tests and errors are fairly easy to diagnose.

For testing we need to build some ELF files containing binman symbols. Add
these to the Makefile and check in the binaries:
u_boot_binman_syms - normal, valid ELF file
u_boot_binman_syms_bad - missing the __image_copy_start symbol
u_boot_binman_syms_size - has a binman symbol with an invalid size

This file contains SPL image without a device tree. Add support for
including this in images.

In some cases we need to read symbols from U-Boot. At present we have a
a few cases which does this via 'nm' and 'grep'.
It is better to use objdump since that tells us the size of the symbols
and also whether it is weak or not.
Add a new module which reads ELF information from files. Update existing
uses of 'nm' to use this module.
