Author: mraudsepp Date: 2009-01-23 11:53:49 +0100 (Fri, 23 Jan 2009) 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.
