Hello, Here are three patches that provide a SerialLib backed by SBI console. Both legacy and DBCN mechanisms are supported in various execution environments and have been tested with UART and HTIF consoles.
MdePkg reviewers: please review MdePkg.dsc changes. This is also available at https://github.com/andreiw/edk2-rv-wip/tree/patchset-2 A CI run is at https://github.com/tianocore/edk2/pull/4252 Compared to v6: - Unify the two SerialLib implementations under one directory and factor out the code somewhat. - Sunil's feedback on correctness. Compared to v5: Rename components as per Michael Kinney's suggestions. Compared to v4: (not sent out). CC MdePkg maintainers, fix copyright date in SecMain.c. Compared to v3 EccCheck fixes. Add MdePkg infs to DSC. Compared to v2: - Probes legacy extension as well. - Encode supported module types in the INF file. This is done using LIBRARY_CLASS, as MODULE_TYPE cannot encode multiple types, so MODULE_TYPE is retained as BASE. - Update INF version and generate brand new GUIDs instead of editing them. - Checked that all patches retain ^M endings.
