Subject: [RFC PATCH V2 0/2] RISCV_EFI_BOOT_PROTOCOL support in U-boot
Date: Fri, 28 Jan 2022 20:48:43 +0530 [thread overview]
Message-ID: <20220128151845.114159-1-sunilvl@ventanamicro.com> (raw)
This patch series 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 patches can be found in:
riscv_boot_protocol_rfc_v2 branch at https://github.com/vlsunil/u-boot.git
These patches are 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_v2 branch at https://github.com/vlsunil/linux.git
Changes since RFC V1:
- Used EFI_ENTRY/EXIT and removed need for static variable
- Addressed other comments from Heinrich
- Added unit test patch
