I'm looking for some initial feedback on the following patches which add support for the UEFI SPI I/O protocol defined in the UEFI Platform Initialization (PI) Specification, Version 1.7 Errata A (April 2020). I'd like to know if the overall approach is acceptable for inclusion in u-boot and if you have any questions or can spot any implementation issues at this stage. I'm planning to follow up with a v2 series addressing any feedback and adding test cases.
