Yes, it's safe.  Some chipsets wont do DMA to the memory region
between 0xc0000-0x100000.  It looks like you have one of those boards.
This can also be specified in the coreboot build - see
src/mainboard/intel/mohonpeak/config_seabios and
src/mainboard/intel/mohonpeak/Kconfig for an example of how to do
