Sorry Star and Liming, For the below patch (removing the alignment check for WorkSpace & SpareArea): https://edk2.groups.io/g/devel/message/89742 Do you think it will impact the FTW service on flash device? Thanks in advance.

The discussion on the patch can be found here: https://review.coreboot.org/c/coreboot/+/62990 Hacking the PCDs could work,, but why would we want to keep an incorrect check? Thanks!
