[edk2-devel] [PATCH v1 1/1] uefi-sct/SctPkg: TCG2 Protocol: Expand BSCap.HashAlgorithmBitmap check

["Amrathesh via groups.io" <amrathesh=arm.com@groups.io>]

Previously, the test only validated SHA-256 in
EFI_TCG2_BOOT_SERVICE_CAPABILITY.HashAlgorithmBitmap,
This update checks all supported SHA256-or-stronger algorithms.
