New Revision: 1119

Added:
   coreboot-v3/mainboard/artecgroup/dbe63/
   coreboot-v3/mainboard/artecgroup/dbe63/Makefile
   coreboot-v3/mainboard/artecgroup/dbe63/cmos.layout
   coreboot-v3/mainboard/artecgroup/dbe63/dts
   coreboot-v3/mainboard/artecgroup/dbe63/initram.c
   coreboot-v3/mainboard/artecgroup/dbe63/irq_tables.h
   coreboot-v3/mainboard/artecgroup/dbe63/stage1.c
Modified:
   coreboot-v3/mainboard/artecgroup/Kconfig
Log:
Start of Artec Group ThinCan DBE63 support.

* 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.
