New Revision: 3203

Added:
   trunk/payloads/coreinfo/nvram_module.c
Modified:
   trunk/payloads/coreinfo/Kconfig
   trunk/payloads/coreinfo/Makefile
   trunk/payloads/coreinfo/coreboot_module.c
   trunk/payloads/coreinfo/coreinfo.c
   trunk/payloads/coreinfo/coreinfo.h
   trunk/payloads/coreinfo/cpuinfo_module.c
   trunk/payloads/coreinfo/pci_module.c
Log:
Add support for an "NVRAM Dump" screen in coreinfo (optional), as well as for
displaying the current date/time in the lower-right corner (optional).

Also, only build/use coreinfo modules which were selected in kconfig. This
makes coreinfo truly modular, and you can save quite a bit of ROM space
by disabling unwanted parts of coreinfo.

Finally, simplify the Makefile a bit by getting rid of MODULES (and only
using OBJECTS).
