Currently there are 3 different "strapping" entries in the coreboot tables, and with the recent addition of fw_config (https://review.coreboot.org/c/coreboot/+/41209), we would also like to add the 64-bit fw_config field (updated here https://review.coreboot.org/c/coreboot/+/45939) to the coreboot table as well. 

In this patch (https://review.coreboot.org/c/coreboot/+/46605), I am proposing to deprecate the 3 current "strapping" entries (board ID, ram code and SKU ID), and add them all to 1 entry, containing board ID, ram code, SKU ID as well as fw_config. This saves the overhead of parsing 4 different entries to obtain board configuration information.

Would like to hear any thoughts on this,
