This series adds few DT related fixes required for Linux EFI stub to work
on RISC-V.

Patch 1 adds the boot hartid property under /chosen node. The related
discussion can be found here.

https://patchwork.ozlabs.org/patch/1233664/
https://lists.denx.de/pipermail/u-boot/2020-March/402085.html

Patch 2 fixes a generic issue in bootefi.

Patch 3 & 4 provide one of the option to update reserved-memory node for Linux.
It depends on Bin's following series in OpenSBI
http://lists.infradead.org/pipermail/opensbi/2020-March/001316.html

The other options are SBI extension and trap/emulate on PMP csr access.
The detaild discussion can be found here.
https://github.com/riscv/riscv-sbi-doc/pull/37

Patch 1 & 2 can be applied indepedently from 3 and 4. I want to keep all
the patches together to provide a holistic view of changes required for
RISC-V UEFI.

Changes from v1->v2:
1. Fix the issue if chosen node is not present.

Changes from previous version:
1. Renamed the DT node property to "boot-hartid" from "efi-boot-hartid".
2. Changed the property type to u32 instead of u64 for RV32 compatibility.

Atish Patra (4):
riscv: Add boot hartid to Device tree
cmd: bootefi: Parse reserved-memory node from DT
riscv: Provide a mechanism for riscv boards to parse reserved memory
riscv: Setup reserved-memory node for FU540
