We have 892 bytes to our disposal in cmos. We can reserve 128 for board/cmos versioning, and reserve even 256 for the bootloader, and still have 512bytes left for coreboot options, which is tons when bits are used properly and when strings are not used.
Most boards I have used have a maximum space of 256 bytes that includes the RTC. Where does the extra come from?
On much of my hardware, the most I can assume is 128 bytes - subtracting many bytes that are weirdly hardware controlled (such as date).
Some of our hardware has 256 bytes.
The io ports only support an 8-bit address I thought?
That said, if newer parts really do have so much data, that is great news.
