REF: https://bugzilla.tianocore.org/show_bug.cgi?id=244 Currently, when software HashLib (HashLibBaseCryptoRouter) and related HashInstanceLib instances are used, PcdTcg2HashAlgorithmBitmap is expected to be configured to 0 in platform dsc. But PcdTcg2HashAlgorithmBitmap has default value 0xFFFFFFFF in SecurityPkg.dec, and some platforms forget to configure it to 0 or still configure it to 0xFFFFFFFF in platform dsc, that will make final PcdTcg2HashAlgorithmBitmap value incorrect. This patch is to add CONSTRUCTOR in HashLib (HashLibBaseCryptoRouter) and PcdTcg2HashAlgorithmBitmap will be set to 0 in the CONSTRUCTOR. Current HASH_LIB_PEI_ROUTER_GUID HOB created in HashLibBaseCryptoRouterPei is shared between modules that link HashLibBaseCryptoRouterPei. To avoid mutual interference, separated HASH_LIB_PEI_ROUTER_GUID HOBs with gEfiCallerIdGuid Identifier will be created for those modules. This patch is also to add check in HashLib (HashLibBaseCryptoRouter) for the mismatch of supported HashMask between modules that may link different HashInstanceLib instances, warning will be reported if mismatch is found.

# Provides hash service by registered hash handler
|
|
#
|
|
# This library is BaseCrypto router. It will redirect hash request to each individual
|
|
# hash handler registered, such as SHA1, SHA256. Platform can use PcdTpm2HashMask to
|
|
# mask some hash engines.
