* Copying of files from other mainboards as a starting point: amd/db800/Makefile artecgroup/dbe62/cmos.layout artecgroup/dbe62/dts amd/db800/initram.c artecgroup/dbe61/irq_tables.h artecgroup/dbe62/stage1
* Kconfig integration. Behind CONFIG_EXPERIMENTAL for now, as the board is not in the market yet.
