The latter is a funny case. I assumed something interesting was going
on but didn't dig into what.

It would be helpful if SoC maintainers would take a look at the
resulting defconfig files with their boards and see if some of the
variation could be removed. E.g. I suspect that some boards disable a
particular option for no particular reason. More uniformity (by
setting defaults in Kconfig however distasteful) will reduce the
defconfig size.

This is not totally size neutral.  I've looked over the changes and in
some cases, strings just get resized slightly, and, it happens.  In
other cases, it comes down to the "fun" games I did on am335x to support
network booting in SPL and the size constrains that can be run into
there, along with just including extra stuff.  It all still links, so
I'll clean up that config afterwards.

As mentioned on a recent thread [1] there is some confusion about whether

it
is very error-prone and time consuming. Also I have had to add some

There are a few strange features of this conversion. The main difficulty
is
that some PowerPC boards do things like this in their board config file:

This means that TPL reuses the SPL options. We can't support this in
Kconfig
so I have added a small number of CONFIG_TPL_xxx_SUPPORT options to cope
with this. This made the conversion more painful than it should have been.

A related issue is boards using a common header file and setting options
only
for SPL:

This is not noticed by moveconfig so we have to clean it up manually. Also
there are a few incorrect things where Kconfig options are set with
#define:

Finally, many defconfig files are not ordered correctly, resulting in
larger
patches than we might like. It would be great to have a solution for this,
perhaps with buildman providing a warning. But it might slow down
development.

The series is fully build-tested (for bisectability) and causes no

[U-Boot] [PATCH v3 00/45] Kconfig: Move CONFIG_SPL_..._SUPPORT to Kconfig

2016-09-12 Thread Simon Glass 
This series moves all the CONFIG_SPL_..._SUPPORT options to Kconfig and
fixes up existing boards to continue to build.

It also adds a few small but useful features to moveconfig.

There is existing work going on in this area, so some of these patches may
be superseded. It has taken me a while to get this building cleanly. But I
have run out of time so want to get this out.

As mentioned on a recent thread [1] there is some confusion about whether an
option means enabling driver support or media support. Andrew's recent
series seems like a good vehicle to tidy that up. But I hope this series
will make it easier.

NOTE: in the v2 series I have tried to use common things in Kconfig to
reduce the diffs in the defconfig files. This has helped a fair bit. But it
is very error-prone and time consuming. Also I have had to add some
exceptions (disabling an option in specific board configs). Overall it was
not a pleasant experience :-(

There are a few strange features of this conversion. The main difficulty is
that some PowerPC boards do things like this in their board config file:

This means that TPL reuses the SPL options. We can't support this in Kconfig
so I have added a small number of CONFIG_TPL_xxx_SUPPORT options to cope
with this. This made the conversion more painful than it should have been.

A related issue is boards using a common header file and setting options only
for SPL:

This is not noticed by moveconfig so we have to clean it up manually. Also
there are a few incorrect things where Kconfig options are set with #define:

Finally, many defconfig files are not ordered correctly, resulting in larger
patches than we might like. It would be great to have a solution for this,
perhaps with buildman providing a warning. But it might slow down
development.

The series is fully build-tested (for bisectability) and causes no failures
for the boards that already pass. The following boards fail for me at
