* MdePkg SmmMemLib: Remove ASSERT in SmmIsBufferOutsideSmmValidStar Zeng2017-06-061-2/+1
| | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=577 Currently the SmmIsBufferOutsideSmmValid() function in SmmMemLib.c will ASSERT in certain conditions. Since this function is a "test" function, it should not be making decisions on how to handle a failure. Handling a failure should be left to the caller. This patch is to remove ASSERT(FALSE) at line 178 of SmmMemLib.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | buffer. This patch adds more check in SmmIsBufferOutsideSmmValid(), to make sure that SMM communication buffer is only EfiReservedMemoryType/EfiRuntimeServicesCode/ EfiRuntimeServicesData/EfiACPIMemoryNVS. So that the communication buffer will not touch any OS memory. The assumption is that a platform reports valid SMM communication buffer at EndOfDxe, because EndOfDxe is last hook point that SMM code can call-out to get memory map information. A platform MUST finish SMM communication buffer allocation before EndOfDxe. If a DXE or OS driver need do communication after EndOfDxe, it can either allocate SMM communication buffer before EndOfDxe and save it, or consume EDKII_PI_SMM_COMMUNICATION_REGION_TABLE table to get general fixed comm buffer. This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS requirement.
