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There is existing work going on in this area, so some of these patches may be superseded.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

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_kconf...
if this series does not break boards ...
bye, Heiko
