Platform/Loongson: Remove minimium memory size limitation

2024-06-12T09:19:38+00:00

Temparory stack memory on PEI is hardcoded now, also minimium memory size 256M is hardcoded now. Here memory map table from fw cfg can be parsed. If there is memory map entry contains pei stack, it can be published as usable memory at PEI stage. Cc: Bibo Mao Cc: Chao Li Signed-off-by: Bibo Mao Signed-off-by: Xianglai Li Reviewed-by: Chao Li

Platform/Loongson: loongarch supports parsing multi-chip flash

2024-02-22T01:58:14+00:00

The current implementation of loongarch NorFlashQemuLib is to parse fdt and think that the first flash address resolved to the NVRAM space, with the evolution of qemu code, loongarch uses the first flash to store UEFI code and the second flash as NVRAM space, so NorFlashQemuLib needs to be able to parse multiple flash base addresses. By default, the first piece of flash other than UEFI code is considered as NVRAM space. Cc: Andrea Bolognani Cc: Bibo Mao Cc: Chao Li Signed-off-by: Xianglai Li Reviewed-by: Chao Li

LoongArchQemuPkg/LsRealTimeClockLib: remove superfluous instance init steps

2023-10-24T13:19:06+00:00

RealTimeClockLib instances are consumed by edk2's EmbeddedPkg/RealTimeClockRuntimeDxe driver. In its entry point function InitializeRealTimeClock(), the driver: (1) calls LibRtcInitialize(), (2) sets the GetTime(), SetTime(), GetWakeupTime() and SetWakeupTime() runtime services to its own similarly-named functions -- where those functions wrap the corresponding RealTimeClockLib APIs, (3) installs EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL with a NULL protocol interface. Steps (2) and (3) conform to PI v1.8 sections II-9.7.2.4 through II-9.7.2.7. However, this means that LibRtcInitialize() (of any RealTimeClockLib instance) should not itself (a) set the GetTime(), SetTime(), GetWakeupTime() and SetWakeupTime() runtime services, nor (b) install EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL. The runtime service pointers will be overwritten in step (2) anyway, and step (3) will uselessly install a second (NULL-interface) EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL instance in the protocol database. (The protocol only serves to notify the DXE Foundation about said runtime services being available.) Clean up LoongArchQemuPkg/LsRealTimeClockLib accordingly. (Note that the lib instance INF file already does not list UefiRuntimeServicesTableLib.) Build-tested only (with "Loongson.dsc").

LoongArchQemuPkg/LsRealTimeClockLib: hide LibRtcVirtualNotifyEvent

2023-10-13T10:11:49+00:00

The RealTimeClockLib class header in edk2 mistakenly declares a function called LibRtcVirtualNotifyEvent(). No component ever calls this function crossing module boundaries; all RealTimeClockLib instances in edk2 and edk2-platforms are supposed to register (and do register) their SetVirtualAddressMap() notification functions. Rename LibRtcVirtualNotifyEvent() to VirtualNotifyEvent(), and make it static, in preparation for removing the LibRtcVirtualNotifyEvent() declaration from the lib class header later.
