Hello,
this patch adds following options, for the use of OEM ROM section, eg: onboard PCI device's BIOS in boot ROM or MAC address saved in boot ROM
ROM_TOTAL_SIZE: the total size of boot ROM ROM_OEM_SIZE: the size of boot ROM used by OEM_ROM section ROM_SIZE: the size of boot ROM used by LinuxBIOS ROM_OEM_START: OEM_ROM start address
OEM ROM exists in the low address end of boot ROM, so default ROM_OEM_SIZE = 0 default ROM_SIZE = ROM_TOTAL_SIZE - ROM_OEM_SIZE default ROM_OEM_START = 0xffffffff - ROM_TOTAL_SIZE + 1
OEM devices should know the offset of their data in OEM ROM, so they can visit their data at address (ROM_OEM_START + oem_my_data_offset)
to use OEM ROM, one should define ROM_TOTAL_SIZE and ROM_OEM_SIZE in mainboard's Options.lb file.
this patch won't break mainboards which defines ROM_SIZE and don't mentions ROM_TOTAL_SIZE and ROM_OEM_SIZE.

don't need.
for evey device that need FW or option you can add fw_rom=.... or rom_address= in Config.lb of src/mainboard.
Also just change ROM_IMAGE_SIZE in section in target Config.lb
