Subject: [v3 PATCH 0/5] Add UEFI support for RISC-V

This series adds UEFI support for RISC-V. Currently, only boot time
services have been added. Runtime services will be added in a separate
series. This series depends on some core EFI patches
present in current in efi-next and following other patches.

U-Boot: Adds the boot hartid under chosen node.
https://lists.denx.de/pipermail/u-boot/2020-April/405726.html

Linux kernel: 5.7-rc1

OpenSBI: master

Patch 1 just moves arm-stub code to a generic code so that it can be used
across different architecture.

Patch 3 adds fixmap bindings so that CONFIG_EFI can be compiled and we do not
have create separate config to enable boot time services. 
As runtime services are not enabled at this time, full generic early ioremap
support is also not added in this series.

Patch 4 and 5 adds the PE/COFF header and EFI stub code support for RISC-V
respectively.

The patches can also be found in following git repo.

https://github.com/atishp04/linux/tree/wip_uefi_riscv_v3

The patches have been verified on Qemu using bootefi command in U-Boot.

Changes from v2->v3:
1. Rebased on top of latest efi patches.
2. Improved handle_kernel_image().

Changes from v1->v2:
1. Rebased on 5.7-rc1.
2. Fixed minor typos and removed redundant macros/comments.

Changes from previous version:
1. Renamed to the generic efi stub macro.
2. Address all redundant comments.
3. Supported EFI kernel image with normal booti command.
4. Removed runtime service related macro defines.

Atish Patra (5):
efi: Move arm-stub to a common file
include: pe.h: Add RISC-V related PE definition
RISC-V: Define fixmap bindings for generic early ioremap support
RISC-V: Add PE/COFF header for EFI stub
RISC-V: Add EFI stub support.
