Description of problem:

EDK2 has already implemented the COCO Measurement Protocol. When starting a COCO virtual machine in direct boot mode, it can measure the initrd and cmdline during the Linux EFI stub phase. Currently, Anolis Cloud Kernel 6.6 does not support this feature yet. Some patches need to be backported from the mainline kernel to enable the measurement of initrd and cmdline.
