We need a way to support more than one board per binary in U-Boot with
device tree. Various methods have been discussed. The one that seems to make
the most sense is to adjust SPL so that it can load a FIT which contains
U-Boot and several device tree binaries. This is how things with with Linux:
load a FIT and select the correct device tree to pass to Linux.
This series:
- Adjusts the build system to optionally build a u-boot.img in FIT format
that includes the U-Boot binary and >1 device tree files
- Adjusts SPL to support loading this
- Adds a way for SPL to determine which device tree to select (by calling a
board-specific function)
- Adjusts SPL to pass this selected device tree to U-Boot when it starts
It would be painful to require an .its file for each board just to support
this feature. In any case various people have commented that it would be
nice not to have to write this file in general. Therefore, this series
enhances mkimage to automatically generate a FIT without a .its file. So far
it understands how to add a main image and a number of device tree files. It
does not support hashing or verified boot as yet.
One problem with the FIT format as it stands is that all the data is inline.
This means that the entire file must be read in order to figure out what
device-tree files are available. It is then possible to copy the images into
place.
This is not really suitable for SPL since copying can be slow, and reading
unnecessary data would make the FIT format less efficient than the legacy
format.
Therefore this series adds a new feature to FIT which allows the images to
be stored immediately after the FIT itself ends. This makes the FIT very
small. It can be read quickly and in its entirety. Then the images can be
loaded one by one as needed. This allows SPL to support FITs containing lots
of images very efficiently.
To achieve this, mkimage is enhanced to convert between the 'normal' and
'external' version of a FIT file. The latter is only used for the SPL loader.
The main difference is that viewing an 'external' FIT will not show the
contents of each image.
This series also includes a few other tidy-ups, such as moving mkimage's
tricky argument-processing code to use getopt().
NOTE: There are a few problems remaining with the Kconfig conversion. I'm
still fiddling with this but thought it best to send this series out for
comment in the meantime.
This series is available at u-boot-fdt/spl-working.

This is how things with with Linux: > load a FIT and select the correct device tree to pass to Linux. I've just skimmed over the git-logs, but I am confused. Please makes it clearer why this is useful. In your way, how SPL is handled? SPL is much more board-specific than U-Boot proper. So, I assume SPL would remain as a per-board image even after achieving one U-Boot proper for multi-boards. Let's say we want to support Board-A, Board-B, Board-C with one U-Boot proper. The U-Boot proper + FIT (including DTB-A, DTB-B, DTB-C) would be generated by one-shot and by one defconfig. But, we would still have to do make board_a_defconfig && make make board_b_defconfig && make make board_c_defconfig && make to generate SPL for each of the three. Is this correct? Supposing my guess is correct, this series would not contribute to decreasing the number of defconfig files. Please explain which problem you are solving with this series. -- Best Regards Masahiro Yamada ^ permalink raw reply [flat|nested] 11+ messages in thread

It won't be just one board. We need this so that we can replicate existing (and very useful) functionality. Today, am335x_evm_config supports Beaglebone White, Beaglebone Black (could be faked enough for U-Boot), AM335x GP EVM, AM335x EVM SK and if you tweak the default UART AM335x IDK EVM. Each of these is different enough that they have their own DT that we will need to pass up to U-Boot, and their own config file. With Simon's series we'll be able to move am335x_evm_config up to DM in SPL and possibly even remove some of the am335x_evm subconfigs we have today, once those specific options also move to Kconfig. -- Tom [-- Attachment #2: Digital signature --] [-- Type: application/pgp-signature, Size: 836 bytes --] ^ permalink raw reply [flat|nested] 11+ messages in thread

So, this series is useful to merge some boards that are different enough to have their own DT, but that are similar enough to share one SPL binary, correct? -- Best Regards Masahiro Yamada ^ permalink raw reply [flat|nested] 11+ messages in thread

Yes. It _may_ even be useful later on to support a more broad set of boards than we do today (ie it's not impossible that one binary could support the TI AM43xx EVMs as well, or all TI EVMs that have the EEPROM that identifies the model, for some narrow scope of boot devices). -- Tom [-- Attachment #2: Digital signature --] [-- Type: application/pgp-signature, Size: 836 bytes --] ^ permalink raw reply [flat|nested] 11+ messages in thread

(Trying to use it on am33xx boards). Many thanks. Yes it should be possible. You will probably need to modify the device tree before booting Linux. In this case however I am not really using the full existing FIT code. It would be easier to use it and it is possible to build full FIT support in SPL. I did it for a project a few years ago but did not upstream it. It does add a bit to the size though.
