Laszlo Ersek 524feaa32f OvmfPkg/RiscVVirt/Sec: clean up ProcessLibraryConstructorList() decl
<Library/PeimEntryPoint.h> declares a bogus
ProcessLibraryConstructorList() for the OvmfPkg/RiscVVirt SEC module. Rely
on AutoGen for (properly) declaring ProcessLibraryConstructorList().
Remove the correct, but superfluous, declaration as well.

Build-tested with:

  build -a RISCV64 -b DEBUG -m OvmfPkg/RiscVVirt/Sec/SecMain.inf \
    -p OvmfPkg/RiscVVirt/RiscVVirtQemu.dsc -t GCC5

Sunil V L 0f9fd06919 OvmfPkg/RiscVVirt: SecEntry: Remove unnecessary assembly directives
llvm fails to resolve _ModuleEntry when these extra directives are
present. ASM_FUNC already takes care what is required.

Sunil V L 7427dd3fc0 OvmfPkg/RiscVVirt: Check "no-map" and mark EfiReservedMemoryType
OpenSBI now marks PMP regions with "no-map" attribute.
So, remove the workaround and add the ReservedMemory only
when no-map is set so that it follows DT spec.

Tuan Phan a8a72fc1ff OvmfPkg/RiscVVirt: SEC: Add IO memory resource hob for platform devices
Normally, DXE driver would add device resource to GCD before start using.
But some key resources such as uart used for printing info at very early
stage.

Those resources should be populated to HOB in SEC phase so they are
added to GCD before MMU enabled.

Andrei Warkentin 0abfb0be6c OvmfPkg: RiscVVirt: Add missing SerialPortInitialize to Sec
If the SerialPortLib had any initialization needed, this
would be skipped in the RiscVVirt Sec. Follow the example
seen elsewhere (ArmVirtPkg PrePi).

Seen with BaseSerialPortLibRiscVSbiLibRam not using DBCN in Sec,
yet using DBCN elsewhere.

Rebecca Cran 8ba392687b OvmfPkg: Update code to be more C11 compliant by using __func__
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.

Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

Sunil V L 71fd87e98a OvmfPkg/RiscVVirt: Support multiple reserved memory ranges
M-mode firmware ranges should not be used by EDK2/OS.
Currently, we search for mmode_resv0 node in FDT and mark it as the
reserved memory in EFI memory map. However, if there are multiple
M-mode firmware ranges, then this will miss those extra ranges
allowing the OS to access the memory and hit a fault.

This issue is exposed since recent opensbi started creating
two ranges for text and data.

Fix this by searching for all reserved memory nodes and marking
them as reserved in the EFI memory map.

Sunil V L f80f052277 OvmfPkg/RiscVVirt: Add Stack HOB
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4350

Currently, stack HOB is not created for the stack memory. This causes
stack memory to be treated as free memory and any memory allocation which
happens at this address causes random memory corruption. Fix this by
creating the stack HOB which marks the memory as BS data.
