I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/34678
to look at the new patch set (#3).
Change subject: common/block/imc: Add Integrated Memory Controller (IMC) driver ......................................................................
common/block/imc: Add Integrated Memory Controller (IMC) driver
IMC is found on certain Xeon processors. On such platforms SPDs are not connected to SMBus on PCH but to dedicated IMC-owned pins. The purpose of this driver is to expose access to the i2c/smbus controller associated with IMC.
Datasheet used: Intel Xeon Processor D-1500 Product Family, Volume 2, reference 332051-001
This driver is largely based on i2c-imc.c Linux driver. https://lwn.net/Articles/685475/
TEST=single/double reads and single writes on Xeon-D1500. Hardware: Open Compute Project Monolake platform.
