Hi,

This RFC patchset starts convertion of ARM defconfigs to use kconfig
fragments and dynamically generate defconfigs. The goals of this
work are to:

- remove duplication between defconfigs

- add a possibility to generate board/SoC/SoC-family/Multi specific
defconfigs in the future (without duplicating defconfigs)

This patchset is only a start of the work for discussion purposes
(I'm not entirely satisfied with the resulting patches):

- the major disadvantage of using kconfig fragments is that it is
now more difficult to update defconfigs

- split on hardware and system specific defconfig fragments is not
obvious and requires more thought

Patches description:

- patch 01 adds defconfigs dynamic generation support (based on
PowerPC code)

- patches 02-21 remove duplication between selected defconfigs
(without splitting them on hardware and system specific parts)

- patches 22-23 start a conversion of multi_v7_defconfig to be
dynamically generated and remove duplication between Multi
defconfig and SoC-family specific defconfigs (only Exynos and
Tegra defconfigs are converted for RFC purposes, defconfigs
are splitted on hardware and system specific parts)

The patchset is against v4.9-rc6 kernel.

FIXMEs:
- add sys_m and sys_m_shared kconfig fragments
- audit hardware/system split
- convert all defconfigs touched by patchset to use:
* hw_y, hw_y_shared, hw_m, hw_m_shared
* sys_y, sys_y_shared, sys_m, sys_m_shared
kconfig fragments
- convert remaining defconfigs
