A common requirement when converting options to Kconfig is to minimise the number of defconfig files that must be changed.
For example, if the pre-Kconfig CONFIG_SCSI option is defined in zynq-common.h, then hopefully it can be added as an 'imply SCSI' to the Kconfig under ARCH_ZYNQ. This allows a single Kconfig change and avoids changing 18 zynq defconfig files.
Unfortunately it is extremely tedious to find which 'implying' configs are best for each option. The moveconfig database helps with this since it is possible to obtain a list of possible implying configs.
To further help with the pain this series automates this work a bit. It uses a Kconfig parser to find the location of each option in the Kconfig tree. Using the information from the database it is then able to automatically add an 'imply' option into the right place if requested by the user. If an 'imply' already exists we can show its location as confirmation that it exists.
