Thu Jan 21 13:19:20 CET 2021


Add basic support for the Hitachi Power Grids kmcent2 board, based
on the NXP QorIQ T1040 SoC.

Changes in v2:
- Sorted header includes as far as possible
- Removed all <common.h> includes
- Fixed block comment formatting
- Removed unnecessary #ifdefs
- Used if with IS_ENABLED() instead of #ifdefs where possible
- Moved MTDPARTS_DEFAULT/MTDIDS_DEFAULT to defconfig
- Fixed misc other formatting issues
