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be superseded.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
present on mainline (which I have not yet looked at):

01: buildman
    blackfin:  +   cm-bf527 bf609-ezkit bf537-stamp
       sparc:  +   grsim grsim_leon2 gr_cpci_ax2000 gr_xc3s_1500 gr_ep2s60
       nios2:  +   10m50 3c120
microblaze:  +   microblaze-generic
    openrisc:  +   openrisc-generic

Changes in v3:
- Move SPL_NET_VCI_STRING into the SPL Kconfig file also
- Rebase on master

Changes in v2:
- Add some notes on this option to moveconfig.py
- Improve the commit message and add one for resyncing with savedefconfig
- Add some notes on this option to moveconfig.py
- Add new patch to convert CONFIG_SPL_NET_VCI_STRING
- Drop CONFIG_SPL_PINCTRL_SUPPORT
- Lots of work to make use of common values across multiple boards
- Added a patch to change 'spear' CONFIGs to upper case

Many thanks for this big work!

Do you have this patches in a git repo?
I want to test this patches with tbot testcase:
https://github.com/hsdenx/tbot/blob/master/src/tc/uboot/tc_uboot_check_kconfig.py

if this series does not break boards ...

Yes it is in u-boot-dm/kconfig-working2.

Thanks! Started from commit:

    Convert CONFIG_SPL_YMODEM_SUPPORT to Kconfig

Hmm ... I get immediately this error:

testing board 10m50 1 / 1196
testing board 3c120 2 / 1196
testing board A10-OLinuXino-Lime 3 / 1196
A10-OLinuXino-Lime u-boot spl bin diff f1da4b556e6ab90d370b5bf827fe7c31 != 94e85eb2c9e7ed2026977d7a814aab6d
testing board A10s-OLinuXino-M 4 / 1196

Hmm... may we have a problem with building SPL binaries reproducable?

First I say No...

pollux:u-boot-none hs [master] $ make mrproper
[...]
pollux:u-boot-none hs [master] $ make A10-OLinuXino-Lime_defconfig
[...]
pollux:u-boot-none hs [master] $ make -s -j8 all

94e85eb2c9e7ed2026977d7a814aab6d  spl/u-boot-spl.bin
pollux:u-boot-none hs [master] $ make mrproper
[...]
pollux:u-boot-none hs [master] $ make A10-OLinuXino-Lime_defconfig

94e85eb2c9e7ed2026977d7a814aab6d  spl/u-boot-spl.bin
pollux:u-boot-none hs [master] $

Same md5sum ... puh.

Applying your first patch, which does not introduce any change for
the A10-OLinuXino-Lime board, and I get the same md5sum ... puh,
the test seems working ...

I try to find out more ... I just have to leave now ...

And sorry for being so annoying ...

bye,
Heiko
