2023-03-30	mb/prodrive/atlas: Rework EEPROM layout structures	Angel Pons
	To avoid having to calculate the length of a struct separately, rework the code to give the struct a tag name, so that `sizeof()` can be used instead. This involves refactoring the `get_emi_eeprom_vpd()` function to return a struct instead of a union, so callers can no longer access the EEPROM data as an array of bytes without additional code, but this array view is only used inside `get_emi_eeprom_vpd()` when reading the data from EMI.

2023-03-24	mb/prodrive/atlas: Implement initial VPD support	Angel Pons
	Atlas stores VPD (Vital Product Data) in an I2C EEPROM, which is only connected to the EC. In order for the host (x86) to be able to access the VPD, the EC reads the EEPROM contents into a buffer in EC RAM and provides the host with read-only access to this EC RAM buffer through EMI (Embedded Memory Interface) 0. The VPD layout is designed to be extensible yet backwards compatible. The code in coreboot uses the revision field to know which fields are valid, and will populate the rest with fallback values. Use the serial number and part number in VPD to populate SMBIOS tables.
