Subject: [edk2-platforms][PATCH 00/30] EDK2 RISC-V port with opensbi v0.9
This is the patch set to incorporate opensbi v0.9 with edk2
RISC-V port. There are many architecture changes to compliant
with the RISC-V SBI implementation (opensbi) and also provide the
flexibility to OEM platform.
Below is the summary of major changes. You can also refer to patch (1/31)
to understand the architecture design.
- Flexibly support privilege modes for edk2 execution phases using PCD.
- M-mode SEC then S-mode all the way to boot OS.
- M-mode SEC and PEI, then S-mode for DXE to boot OS.
- M-mode firmware all the way to S-mode OS.
Default is M-mode SEC then S-mode all the way to boot OS.
Still have to implemente priviledge mode switching for PEI to DXE and
BDSto Boot OS.
- Apply opensbi firmware domain solution to protect firmware regions using
FDF/PCD.
- Provide Platform SEC PPI library that can be executed in either M-mode or
S-mode PEI phases according to OEM platform definition.
- Determine boot hart using Device Tree or PCD. This allows OEM to
flexibly select the desired HARTs for booting system. Non-boot HARTs
can be used for other applications/purposes.
- Provide an edk2 library wrapper of opensbi platform functions. This
allows OEM to have procedures that hooks before or after the certain
opensbi platform functions.
- Other patches to adopt opensbi v0.9.
