This is a patch series that contains:
1.loongarch add flash device driver.
2.loongarch add nvme device driver.
3.Optimize the mmu lib of loongarch.
4.Enable zero address protection.
v3 changes:
- split flash driver patch.
v2 changes:
- Split the MMU lib-related patches further.
- Remove the for loop of flash information lookup
in VirtNorFlashPlatformLib Because the Loongarch
virtual machine only emulates one flash .
- Add the necessary comments in VirtNorFlashPlatformLib.
- Remove the hard coding associated with the Flash base address.
- Optimize the process of converting huge pages to
page table entries in MMU lib.
xianglai li (8):
Platform/Loongson: add bootmode support.
Platform/Loongson:add nvme device driver for loongarch.
Platform/Loongson: Add pflash driver.
Platform/Loongson: Support pflash for loongarch.
Platform/Loongson: Modify the page table entry access priority.
Platform/Loongson: Optimize page table entry null determination.
Platform/Loongson: Optimize the huge page and page entry conversion.
Platform/Loongson: Enable zero address protection.
