I thought we already reach agreement that specific patch for converting all to kconfig would be after this patch set, since it needs more time for the tool to execute all the convertion, right?
SPL_FPGA_SUPPORT is Kconfig'd already, so do not add it into include/configs/*h . If there is a bug, fix it.
I don't think that is bug, this is how the build order is designed, Kconfig is build 1st, then only compiling the header/C files. So i would suggest all related/dependency CONFIG put in one place,either all in Kconfig or in header file.
If we put anything which is already using Kconfig into the header file again, what's the point of using Kconfig ?
So, i suggest to submit a seprate patch for converting all to Kconfig after this patchset, or i can pull this patch into this patchset.
If you prefer adding SPL_FPGA_SUPPORT into this patchset, i need to rerun the tool for this macro, because a lot defconfigs require FPGA feature enabled in SPL build. I also need to run all defconfigs compilation and make sure above example is not hit, otherwise FPGA driver could be failed in the build.
What do you think?
I think the SPL_FPGA_SUPPORT is already Kconfig-ified and I don't quite understand what's the problem you have, sorry. But I am positive any Kconfig option shouldn't be selected in the config header file.
How about i just pull the patch convert all to Kconfig into this patch set, and this will replace the patch 3. I just recalled why i need to to enable the SPL FPGA build on patch 4 because patch 5 FPGA manager already being moved to drivers/fpga/ hence some functions from FPGA manager are required in SPL phase. In this arrangement, we can avoid duplicate effort and time spending since we already have that Kconfig patch.
I'll check the patches.
Are you OK?
I'm fine, thank you for your concern.
