Update shim-install to set the TPM2 SRK algorithm (bsc#1213945)
Limit the requirement of fde-tpm-helper-macros to the distro with
 suse_version 1600 and above (bsc#1219460)

Update to version 15.8:
Security issues fixed:

mok: fix LogError() invocation (bsc#1215099,CVE-2023-40546)
avoid incorrectly trusting HTTP headers (bsc#1215098,CVE-2023-40547)
Fix integer overflow on SBAT section size on 32-bit system (bsc#1215100,CVE-2023-40548)
Authenticode: verify that the signature header is in bounds (bsc#1215101,CVE-2023-40549)
pe: Fix an out-of-bound read in verify_buffer_sbat() (bsc#1215102,CVE-2023-40550)
pe-relocate: Fix bounds check for MZ binaries (bsc#1215103,CVE-2023-40551)

The NX flag is disable which is same as the default value of shim-15.8, hence, not need to enable it by this patch now.

Generate dbx during build so we don't include binary files in sources Don't require grub so shim can still be used with systemd-boot Update shim-install to fix boot failure of ext4 root file system
 on RAID10 (bsc#1205855)

Adopt the macros from fde-tpm-helper-macros to update the
 signature in the sealed key after a bootloader upgrade


Update shim-install to amend full disk encryption support

Adopt TPM 2.0 Key File for grub2 TPM 2.0 protector Use the long name to specify the grub2 key protector cryptodisk: support TPM authorized policies

Do not use tpm_record_pcrs unless the command is in command.lst


Removed POST_PROCESS_PE_FLAGS=-N from the build command in shim.spec to
 enable the NX compatibility flag when using post-process-pe after
 discussed with grub2 experts in mail. It's useful for further development
 and testing. (bsc#1205588)");
