New Revision: 1015

Modified:
   coreboot-v3/mainboard/artecgroup/dbe61/initram.c
Log:
artecgroup/dbe61: Use dbe61c specific variables and macros instead of generic ones

This is in preparation of dbe61a handling addition.

Uses DIMM_DBE61C and DIMM_EMPTY instead of generic DIMM0/DIMM1, and
spd_table_dbe61c instead of spd_table.

Also removes a completely unused smb_devices structure definition.
