[RFC PATCH 0/1] RISCV_EFI_BOOT_PROTOCOL support in U-boot

[Sunil V L]

This patch adds the support in u-boot for new RISCV_EFI_BOOT_PROTOCOL for RISC-V
UEFI platforms. This protocol is required to communicate the boot hart ID to the
bootloader/kernel which need to follow the EFI calling conventions.

The latest draft spec of this new protocol is available at
https://github.com/riscv-non-isa/riscv-uefi/releases/download/1.0-rc2/RISCV_UEFI_PROTOCOL-spec.pdf

This u-boot patch can be found in:
riscv_boot_protocol_rfc_v1 branch at https://github.com/vlsunil/u-boot.git

This patch is tested in qemu. To fully test the feature, we need
Linux changes which consume this protocol.
The linux patch can be found in:
riscv_boot_protocol_rfc_v1 branch at https://github.com/vlsunil/linux.git
