Dear All.

Debugging with ConfigureAdvancedSecureBoot.
If InstallSMR or HSE_InstallCoreResetEntry is successful, the secure boot related bit is not toggled when HSE status is retrieved.
(However, it is normal when ConfigureSHESecurureBoot is used.)
Is this behavior intended? Why not support ConfigureAdvancedSecureBoot?

Hi @squirrel_rin 

different status bits are used for SHE secure boot and Advanced secure boot. Isn't that the problem? From Secure boot app note:
